I’m sure this is not helpful but, my grandmother born about 1892ish was called Sarah Harkin. My mom told me that information. She
:-\told me lots but I was young and stupid. 40 years later I now wish I remembered or wrote everything down.
Anyway, my Sarah Harkin went to Canada (no idea when) but married before or after, my grandfather John Hughes (who was a twin) and they had two children James and Mary (my mom). Not that interesting I can hear you say, however they had a relation, that my mom called Aunt Cassie. Married name Dixon. Cassie lived in America and persuaded my grandfather to cross the boarder into the USA and they became bootleggers. Cassie was heavly involved in this. He was in and out of clink as my mom called it, and she and her brother was in and out of children’s homes. In 1932 :-\The family, that now had another daughter called Cecelia (American citizen) all got deported back to ireland. This is obviously not much without paperwork, but if they were related, it might give you some clues
