My name is Gene Erickson, and I am researching my gg grandparents who were farmers and lived near or in Dumbarton in 1848 when their first son was born. My grandfather, born in the US, always referred to his family as Scotch-Irish, which infers that they emigrated from Ireland to Dumbarton to better their lives as farmers. Was this common for Dunbartonshire in the first half of the 19th century? Why? Thank you.
