BCG Evidence Analysis
Professional Genealogical Standards Applied to Occupational Tracking
A comprehensive evaluation of 40+ sources following Board for Certification of Genealogists methodology
Research Objective
Primary Question: How can we identify a specific John Kenny among dozens of similarly-named individuals in Brooklyn, Kings County, New York, during the period 1850-1888, and establish his family connections to both the Kenny and McKenny families?
Secondary Question: Can occupational tracking serve as a reliable methodology for distinguishing individuals when traditional name-based genealogy fails due to surname frequency?
The Research Challenge
Brooklyn's 19th-century Irish immigrant community presents a significant genealogical challenge: common surnames combined with limited vital records before 1866 make individual identification extremely difficult. The surname "Kenny" was particularly prevalent, with dozens of John Kennys appearing in Brooklyn records during the research period.
Traditional genealogical approaches—matching names, ages, and birthplaces—prove insufficient when multiple individuals share these characteristics. A more distinctive identifier was needed to track our subject across time and record types.
The Solution: Occupational Tracking
The occupation "Mat Maker" (also recorded as "matmkr," "matmaker," and "Mat Weaver") appears infrequently enough in Brooklyn records to serve as a reliable unique identifier. By tracking this distinctive occupation across census records, city directories, and related family members, we can distinguish our John Kenny from others sharing his name.
Source Classification
Original Sources
The following sources are original records created at or near the time of the events they document:
Vital Records
• Death Certificates - James Kenny (1875), Eliza Kenny (1887), John Kenny (1888), George McKenny (1870), Margaret Kenny (1884), infant Margaret Kenny (1884), Mary Agnes Robertson (1924), Joseph Robertson (1924)
• Birth Certificates - Lillian Robertson (1905), Helen Robertson (1907), Joseph J. Robertson (1920)
• Baptismal Certificate - Mary Agnes Kenny (1882)
Census Records
New York State Census: 1855, 1875, 1915
City Directories
Directory Reliability:
City directories were compiled annually from information provided directly by householders or gathered by canvassers. While not government records, they provide contemporary evidence of residence and occupation with reasonable accuracy.
Derivative Sources
Indexes and Applications
• Marriage Indexes (Brooklyn)
• Social Security Applications and Claims Index
Information Classification
Primary Information
Information provided by participants in or eyewitnesses to the events:
Direct Participant Records
• Census returns - information from household members
• Directory entries - information from householders
• Birth certificates - information from parents/attending physician
• Death certificates - information from attending physician (cause of death)
Secondary Information
Information provided by non-eyewitnesses or recorded after the fact:
Informant-Provided Records
• Social Security applications - information about parents provided decades after their deaths
• Obituaries - compiled from family information
Evidence Classification
Direct Evidence
Evidence that answers the research question without requiring additional interpretation:
Identity Evidence
• 1870 Census: "Mat Maker"
• 1879 Directory: "matmkr"
• 1880 Directory: "matmkr"
• 1888 Directory: "matmaker"
Analysis:
The consistent appearance of this distinctive occupation across four different record types over 18 years provides direct evidence identifying this specific John Kenny. The occupation is uncommon enough to serve as a reliable unique identifier.
Family Relationship Evidence
• 1882 Baptism: "Parents: John Kenny and Margaret McKenny"
• 1924 Death Certificate: "Father: John Kenny; Mother: Margaret McKenny"
Parentage of Elizabeth "Lillian" Kenny:
• 1920 Marriage: "Father: John; Mother: Margaret McKinney"
• Social Security Application: "Father: John; Mother: Margaret McKernry"
Indirect Evidence
Evidence that requires inference or combination with other evidence:
Family Trade Cluster
• 1875 Census: Eliza Kenny - "Hatter"; James Kenny - "Mat Weaver"
• 1888 Death Certificate: John Kenny - "Hatter"
Analysis:
The clustering of hat-making and mat-making occupations within the family provides indirect evidence that these individuals are related. Mat weaving and mat making are allied trades within the hat-making industry, explaining the occupational connection between brothers James and John.
Co-residence Evidence
• 1880 Directory: Same co-residence at 75 Walworth
• 1880 Census: John Kenny household includes "Eliza Kenny (Mother)"
Analysis:
Directory entries showing mother and son at the same address, combined with the census explicitly identifying Eliza as John's mother, provides indirect evidence of the family relationship that corroborates the marriage record naming Richard and Eliza as parents.
Tuberculosis Pattern
• 1884: Margaret Kenny - "Pulmonary Consumption"
• 1888: John Kenny - "Pulmonary Phthisis"
• 1924: Mary Agnes Robertson - "Pulmonary Tuberculosis"
Analysis:
The pattern of tuberculosis deaths across three generations—father-in-law, daughter, son-in-law, granddaughter—provides indirect evidence of family connection. While not proof of relationship on its own, the pattern corroborates connections established by other evidence.
Negative Evidence
The absence of expected evidence that provides information:
Richard Kenny's Absence
• 1855 Census: Eliza as "Mother" with adult sons
• 1862 Directory: "Eliza wid." (widow)
Analysis:
Richard Kenny's absence from all records after the 1843 marriage, combined with Eliza's consistent designation as widow, provides negative evidence supporting his death circa 1854 (before comprehensive death records began in Brooklyn).

Proof Argument
Conclusion
The evidence conclusively establishes that John Kenny, mat maker of Brooklyn, was the son of Richard Kenny and Eliza Kenny (married 1843), brother of James Kenny, husband of Margaret McKenny (daughter of George McKenny and Ann Lynch), and father of Elizabeth "Lillian" Kenny (b. 1879) and Mary Agnes Kenny (b. 1882).
Supporting Evidence Summary
Identity Proof
John Kenny is uniquely identified through:
2. Co-residence with mother Eliza (wid. Richard) at 75 Walworth in 1879-1880 directories
3. Family trade cluster - brother James as "Mat Weaver," mother Eliza as "Hatter"
4. Consistent geographic presence in Brooklyn Wards 5→7→9→21
Parentage Proof
John Kenny's parentage (Richard Kenny & Eliza Kenny) is established through:
2. 1850-1875 Census records - John consistently in Eliza's household as son
3. 1879-1880 Directories - "Elizabeth wid. Richard" at same address as John
4. 1880 Census - "Eliza Kenny (Mother)" in John's household
Marriage Proof
John Kenny's marriage to Margaret McKenny is established through:
2. 1882 Baptism - "Parents: John Kenny and Margaret McKenny"
3. 1884 Death Certificate - Margaret Kenny, married, certificate to "John Kenny"
4. McKenny family censuses - Margaret absent from mother Ann's household after 1875
Children Proof
John and Margaret Kenny's children are established through:
• 1880 Census: "Eliza Kenny (Daughter, 10/12 months)"
• 1920 Marriage: "Father: John; Mother: Margaret McKinney"
• Social Security: "Father: John; Mother: Margaret McKernry"
Mary Agnes Kenny (b. 1882):
• 1882 Baptism: "Parents: John Kenny and Margaret McKenny"
• 1924 Death: "Father: John Kenny; Mother: Margaret McKenny"
Infant Margaret Kenny (b. 1884, d. 1884):
• 1884 Death Certificate: parents' birthplace U.S.; delivered to John Kenny
Corroborating Evidence
Tuberculosis Pattern
The pattern of tuberculosis deaths provides corroborating evidence for family connections:
• Margaret Kenny (John's wife): TB, May 24, 1884
• John Kenny: TB, November 30, 1888
• Mary Agnes Robertson (John's daughter): TB, January 26, 1924
This multi-generational pattern of the same disease within a connected family group provides independent corroboration of the established family relationships.
Caretaking Pattern
Post-orphaning care arrangements confirm family connections:
• 1910 Census: Lillian Kenny as "niece" in Mary F. MacKinney's household
• 1920 Marriage: Mary MacKinney witnesses Lillian's marriage
• 1935 Obituary: Mary F. MacKinney "survived by several nieces"
Methodology Validation
Occupational Tracking as Identification Tool
Findings
This case study demonstrates that occupational tracking can serve as a reliable methodology for distinguishing individuals when traditional name-based genealogy fails. The approach is most effective when:
1. The occupation is distinctive enough to serve as a unique identifier
2. The occupation appears consistently across multiple record types
3. The occupation can be traced over an extended time period
4. Related family members share allied trades (corroborating family identification)
5. Other evidence (residence, age patterns) corroborates the occupational identification
Application to Other Research
This methodology can be applied to other cases involving:
• Pre-vital records era research
• Urban areas with high population density
• Specialized trades with distinctive terminology
• Multi-generational occupational patterns
