E. Irish Family Records (13 Sources)
Henry Hamall, Mary McMahon, and Donaghmoyne Origins (1841-1874)
Henry Hamall & Mary McMahon - Marriage Record (1841)
Donaghmoyne parish, County Monaghan, Ireland
What This Proves:
Henry Hamall married Mary McMahon in Donaghmoyne parish, County Monaghan, Ireland in 1841. This foundational document proves: (1) Owen's parents' names and marriage location, (2) Irish origins in County Monaghan, (3) Marriage occurred 6 years before Owen's birth (1847), (4) Family was in Ireland during pre-Famine period, (5) Mary's maiden name: McMahon (critical for tracing maternal line). The 1841 marriage establishes the family in Donaghmoyne parish where Griffith's Valuation (1861) would later show multiple Hamill families in adjacent townlands. Henry and Mary would have at least four children: Mary (1847-1851), Michael (c. 1850), Owen (1847-1898), and Mary Ann (1853-1909). The family emigrated to Montreal c. 1850 during the Great Famine, where Henry died in 1854 leaving Mary a widow with four young children.
Owen Hammel & Ann King - Marriage Record (1846)
1846, Donaghmoyne parish, County Monaghan
What This Proves:
DNA-VALIDATED EXTENDED FAMILY CONNECTION: Owen Hammel (NOT our Owen Hamall who was born 1847) married Ann King in Donaghmoyne in 1846. DNA testing (2024-2025) proved that this Owen Hammel & Ann King couple is biologically related to Henry Hamall & Mary McMahon (our Owen's parents). This validates: (1) The extended Hamill family network in Donaghmoyne parish, (2) Geographic clustering of related families in the same parish, (3) The tight-knit nature of the Irish community before emigration. This is the second of four interconnected Donaghmoyne marriages all proven through DNA to be part of the same extended biological family network. The surname variation (Hammel vs. Hamall) was common in Irish records.

Charles McCanna & Susan Hamill - Marriage Record (1857)
1857, Donaghmoyne parish, County Monaghan
What This Proves:
DNA-VALIDATED EXTENDED FAMILY CONNECTION: Charles McCanna married Susan Hamill in Donaghmoyne in 1857. DNA evidence (2024-2025) confirmed this couple is biologically related to Henry Hamall & Mary McMahon. This marriage proves: (1) The Hamill surname continued in Donaghmoyne even after Henry's branch emigrated (c. 1850), (2) Susan Hamill represents another branch of the extended family, (3) The McCanna-Hamill union demonstrates intermarriage patterns in the parish. This is the third of four interconnected marriages validated by DNA.

James Hamill & Anna Gartlan - Marriage Record
Donaghmoyne parish, County Monaghan
What This Proves:
DNA-VALIDATED CONNECTION — EXPLAINS GARTLAN CLUSTER: James Hamill (confirmed as the James Hamill 1827-1914 from Dian townland in Griffith's Valuation) married Anna Gartlan in Donaghmoyne parish. DNA testing (2024-2025) confirmed this couple is biologically related to Henry Hamall & Mary McMahon. This marriage is particularly significant because it explains the DNA evidence: (1) Why DNA matches cluster around both "Hamill" and "Gartlan" surnames, (2) The Gartlan connection is through the HAMILL side (James Hamill married Anna Gartlan), NOT through Kate Griffith's family, (3) This Hamill-Gartlan intermarriage created the genetic signature that appears in descendant DNA. This is the fourth of four interconnected Donaghmoyne marriages all proven by DNA to be part of one extended biological family network.

Mary Hamill - Baptism Record in Ireland (1847)
Irish Catholic Baptism Record - January 1, 1847
Mary Hamill, daughter of Henry Hamill and Mary McMahon - born in Donaghmoyne, County Monaghan, Ireland—Owen's older sister
Owen's Lost Sister - Famine Baby Who Didn't Survive: Mary Hamill was Owen's older sister, born January 1, 1847 in Donaghmoyne, County Monaghan, Ireland—right in the middle of the Great Famine (1845-1852). She lived only four years, dying in Montreal in 1851 shortly after the family's emigration to Canada. Mary's birth during the famine and her early death demonstrate the crushing hardships facing the Hamill family even before they left Ireland. Owen was born the same year as his sister Mary (1847), making them close in age. When Mary died in Montreal at age four, Owen was also only four years old—old enough to remember his sister's death, his first experience with the family tragedy that would later claim four of his own children.
What This Proves:
This baptismal record provides critical documentation of Mary Hamill's birth and establishes her as Owen Hamall's older sister. The record confirms:
- Child's Name: Mary Hamill
- Birth Date: January 1, 1847
- Birthplace: Donaghmoyne Parish, County Monaghan, Ireland
- Father: Henry Hamill
- Mother: Mary McMahon
Parents Confirmed: This record definitively identifies Owen's parents as Henry Hamill and Mary McMahon, providing independent verification of the family's Irish origins. Mary Hamill was Owen's older sister by several months. Owen would have been approximately four years old when his sister Mary died in Montreal in 1851—old enough to remember her and to experience grief at her loss.
Parish: Donaghmoyne, County Monaghan, Ireland
Baptism Date: January 1, 1847
Father: Henry Hamill
Mother: Mary McMahon
Historical Context: Born during "Black '47," deadliest year of Great Famine
Mary Hamall - Death/Burial Record in Montreal (1851)
Montreal Catholic Death/Burial Register - 1851
Mary Hamall, age 4, daughter of Henry Hamall and Mary McMahon—died in Montreal shortly after family's emigration from Ireland
Emigration and Early Loss: Mary Hamall died in Montreal in 1851 at age four, shortly after the family's emigration from Ireland. Her death proves the Hamill family had arrived in Montreal by 1851 (likely 1850), fleeing famine conditions in County Monaghan. Mary survived birth during "Black '47," survived the famine years in Ireland, survived the dangerous Atlantic crossing, but died within a year or two of arriving in Canada. For young Owen (age 4), his sister's death was his first experience with family loss, foreshadowing the devastating child losses he would experience with his own children forty years later.
- January 1, 1847: Mary Hamill born in Donaghmoyne, Ireland
- Late 1847: Owen born in County Monaghan
- Circa 1850: Family emigrates to Montreal (fleeing famine)
- 1851: Mary Hamall dies in Montreal at age 4
- 1853: Mary Ann born in Montreal
- 1854: Father Henry Hamall dies in Montreal
What This Proves:
This death/burial record provides crucial documentation of Mary Hamall's death in Montreal and confirms the family's emigration timeline. Mary's 1851 death in Montreal definitively proves the Hamill family had emigrated from Ireland and settled in Montreal by 1851. The family fled Ireland during the final years of the Great Famine (1845-1852), joining tens of thousands of Irish emigrants who sought survival in North America.
Death Location: Montreal, Quebec, Canada
Death Date: 1851
Age at Death: Approximately 4 years
Father: Henry Hamall
Mother: Mary McMahon
Significance: Proves family arrived in Montreal by 1851
Michael Hamall - Baptism Record (1851)
Baptismal register page from Basilique Notre-Dame, Montreal, 1851
Detail of Michael Hamall's baptism entry identifying parents as Henry Hamall (journalier/day laborer) and Mary McMahon (immigrant)
What This Proves:
Michael Hamall was baptized June 30, 1851 at Basilique Notre-Dame, Montreal. His parents were Henry Hamall (journalier/day laborer) and Mary McMahon (immigrant). Michael was born approximately one year before baptism (c. 1850). This baptism record provides crucial evidence for establishing the family's emigration timeline. Michael's birth in Canada approximately one year before the June 1851 baptism places the family's arrival in Montreal around 1850, consistent with Famine-era emigration from County Monaghan.
1861 Canada East Census: Michael Hamel in Thornton Household
1861 Canada East Census showing the Thornton-Hamall household
What This Proves:
The 1861 Canada East Census shows the Thornton-Hamall household living together in Montreal. Listed are: Patrick Thornton (head of household), M. Thornton, O. Hamel (Owen), M. Hamel (Mary), M. Hamel (Michael), and William Thornton—documenting the blended family ten years after Michael's baptism. This census is the last known record showing Michael Hamall with his family.
1897 Chicago City Directory: Michael J. Hamall (Possible)
1897 Chicago city directory listing for "Hamall Michael J. bridgebuilder bds. 94 Sholto"
What This Proves:
A Michael J. Hamall was living at 94 Sholto Street in 1897 working as a bridgebuilder. The 94 Sholto address connection to Kate Hamall (Owen's widow) suggests possible family relationship. However, without documentation connecting this Michael J. Hamall to the Michael baptized in Montreal in 1851, positive identification remains speculative. The 36-year gap between 1861 and 1897 is too large to bridge without additional evidence.
Mary Ann Hamall - Baptism Record (1853)
Baptismal register page, April 10, 1853, Basilique Notre Dame, Montreal
What This Proves:
CRITICAL DOCUMENT: Mary Ann's baptism record explicitly lists her parents as "Henry Hamell" and "Mary McMahon," providing contemporary documentation of Owen's parents' names. This proves: (1) Henry and Mary were Owen's parents (confirmed through Mary Ann as Owen's sibling), (2) The family was living in Montreal by 1853, (3) Mary Ann was born March 17, 1853, (4) Henry was still alive in 1853 (he would die in 1854). Mary Ann's descendants would provide crucial DNA matches validating the family relationships.
Mary Ann Hammell - Marriage Record (1879)
Detail from 1879 marriage record showing Mary Ann Hammell as daughter of deceased Henry Hammell and Mary McMahon
Full page of 1879 marriage register showing the marriage of Mary Ann Hammell to William F. Byron
What This Proves:
Mary Ann Hammell, daughter of deceased Henry Hammell and Mary McMahon, married William Byron (brass finisher). This marriage record serves two critical purposes: First, it provides independent verification of Mary's parents as Henry Hammell and Mary McMahon, corroborating the 1853 baptism record. Second, it creates the surname lineage (Byron) through which modern DNA researchers can identify and connect with Mary's descendants. DNA matches bearing the Byron surname can be traced back through this 1879 marriage to Mary Hamall, and ultimately to Henry Hamall and Mary McMahon.
1861 Canada East Census: Mary Hamel in Thornton Household
1861 Canada East Census showing Mary Hamel (age 8) in the Thornton household alongside her brothers Owen and Michael
What This Proves:
The 1861 Canada East Census shows Mary Hamel (age 8) living with Patrick Thornton, O. Hamel (Owen), M. Hamel (Michael), and William Thornton. This census is crucial for establishing that Owen, Mary, and Michael were siblings living in the same household. This sibling relationship is later validated by DNA evidence from Mary's descendants matching Owen's descendants.
1901 Census: Mary Byron in Montreal
Mary Byron (née Hamall) age 48, living with husband William Byron
What This Proves:
Mary Byron, age 48, married, wife of William F. Byron (brass finisher), living in St. Anne's Ward, Montreal. This census documents Mary Byron living in Montreal at the turn of the 20th century. Her Byron descendants provide the DNA lineage that connects back to Henry Hamall and Mary McMahon. In 1901, while Mary Byron was living in Montreal, her brother Owen had been dead for three years (died 1898 in Chicago).
Henry Hamall - Death Record (1854)
[Image Placeholder: Death/Burial Record]
1854, Montreal, age 37
What This Proves:
Henry Hamall died in Montreal in 1854 at age 37, leaving widow Mary McMahon with three young children: Michael (c. 4), Owen (7), and Mary Ann (1). This death proves: (1) Henry's approximate birth year: 1817, (2) He died just 3-4 years after emigrating from Ireland, (3) Mary McMahon became a widow with three dependent children, (4) The family faced economic crisis with loss of the male breadwinner. Henry's death set in motion Mary's remarriage to Patrick Thornton in 1855, which created the blended family and explains the half-brother relationship between Owen and William Thornton.
Patrick Thornton & Mary McMahon - Marriage Record (1855)
1855, Montreal - widow's remarriage
What This Proves:
CRITICAL EXPLANATION DOCUMENT: Mary McMahon (explicitly identified as "widow of Henry Hamall") married Patrick Thornton in Montreal one year after Henry's death. This marriage created the blended family and explains William Thornton's relationship to Owen. The marriage proves: (1) Mary remarried quickly after Henry's death, (2) Patrick Thornton became stepfather to Owen, Michael, and Mary Ann, (3) The marriage would produce William Thornton (born c. 1856), (4) This explains the 1861 census showing the blended household. Children from both marriages were raised together.
Mary McMahon - Death Record (1874)
[Image Placeholder: Death/Burial Record]
September 19, 1874, Montreal
What This Proves:
Mary McMahon died September 19, 1874 in Montreal at approximately age 54. Burial record identifies her as "Mary McMahon, widow of the late Henry Hammel." This proves: (1) Mary's death date and location (Montreal, NOT Chicago), (2) She was identified by her first husband's name even 20 years after his death, (3) Mary died when Owen was approximately 27 years old, (4) Both of Owen's parents died before his marriage to Kate (1879).
Griffith's Valuation 1861 - Donaghmoyne Parish
[Image Placeholder: Griffith's Valuation Pages]
Multiple Hamill families in adjacent townlands
What This Proves:
Griffith's Valuation documents geographic clustering of Hamill families in Donaghmoyne parish. IMPORTANT: Only James Hamill in Dian townland is confirmed as related (1827-1914, married Ann Gartlan). The Henry Hamill and Owen Hamill listed are UNKNOWN identities—they could be relatives but cannot be confirmed. The valuation proves: (1) Multiple Hamill families lived in adjacent townlands, (2) Geographic clustering suggests possible kinship, (3) James Hamill in Dian is documented through DNA evidence.
1824 Tithe Applotment - Henry Hamil, Edengilrew
[Image Placeholder: Tithe Applotment Books]
Henry Hamil, 1824, Edengilrew, Donaghmoyne
What This Proves:
A Henry Hamil appears in the 1824 Tithe Applotment Books for Edengilrew townland, Donaghmoyne. Since our Henry Hamall was born approximately 1817, he would have been only 7 years old in 1824. This Henry Hamil in 1824 is likely our Henry's father or uncle. The record proves: (1) The Hamill family had presence in Donaghmoyne going back to at least 1824, (2) Generational continuity in the area. This earlier generation documentation helps establish the depth of Hamill family roots in County Monaghan.
F. DNA Evidence & Extended Family (4 Sources)
Genetic Validation of Documentary Findings
Four DNA-Validated Donaghmoyne Marriages:
DNA testing (2024-2025) proved biological relationships between four couples who all married in Parish of Donaghmoyne, County Monaghan: (1) Henry Hamall & Mary McMahon (1841) — Owen's parents; (2) Owen Hammel & Ann King (1846) — related Hamill line; (3) Charles McCanna & Susan Hamill (1857) — extended family; (4) James Hamill & Anna Gartlan — explains Gartlan DNA cluster. All four couples proven to be part of one extended biological family network in County Monaghan.
DNA Match: CR (Catherine Robinson) - 19 cM
What This Proves:
CRITICAL DNA VALIDATION: CR matches the researcher at 19 cM, consistent with a 4th cousin relationship. CR descends from Mary Ann Hamill Byron (Owen's sister). This DNA match corroborates that Owen and Mary Ann Hamill Byron shared the same parents (Henry Hamall and Mary McMahon). Common ancestors: Henry Hamall (1817-1854) & Mary McMahon (c. 1820-1874).
Shared DNA: 19 cM across 1 segment
Relationship: 4th cousin
Common Ancestors: Henry Hamall & Mary McMahon
DNA Match: DK - 19 cM
What This Proves:
DK provides independent validation through a different descendant line of Mary Ann Hamill Byron. DK matches at 19 cM (identical to CR's match amount). Having two independent DNA matches through the same ancestral line significantly strengthens the case. Both CR and DK matching at 19 cM through Mary Ann eliminates random chance and confirms biological relationships.
Shared DNA: 19 cM across 1 segment
Relationship: 4th cousin
Common Ancestors: Henry Hamall & Mary McMahon
Gartlan Family DNA Cluster Matches
What This Proves:
Multiple DNA matches cluster around descendants of Gartlan families who intermarried with Hamill families in Donaghmoyne. IMPORTANT: These matches connect through the HAMILL family line in Ireland, NOT through Kate Griffith. The Gartlan cluster validates James Hamill (1827-1914) married Ann Gartlan, and demonstrates extended family network in County Monaghan.
Match Range: 14-35 cM
Geographic Origin: Donaghmoyne parish, County Monaghan, Ireland
Note: Connection through HAMILL line, not Griffith line
McMahon Family DNA Cluster Matches
What This Proves:
A separate DNA cluster validates Mary McMahon as Owen's mother through matches to McMahon family descendants from County Monaghan. This maternal line cluster is distinct from the paternal Hamill/Gartlan cluster. The cluster analysis demonstrates the expected pattern—matches through both paternal (Hamill) and maternal (McMahon) lines validate Owen's documented parentage.
Match Range: 14-35 cM
Significance: Maternal line (Mary McMahon) validation
Note: Distinct cluster from paternal Hamill/Gartlan line
