Years of History

In rural County Monaghan, Ireland, a farming couple raised eleven children through decades of agricultural hardship and the great wave of Irish emigration. James Hamill and Ann Gartlan never left their townland of Dian — but their children scattered across three continents. This series tells their stories.

Four sons emigrated to America: Patrick, Peter, and Henry to St. Louis, Missouri; James to the copper mining country of Anaconda, Montana. Two daughters — Anna and Bridget — stayed in Ireland, marrying into neighboring families. Their headstone at Old Broomfield Cemetery, inscribed "JAMES HAMILL, DIAN," anchors 160 years of documented family history.
