My 2nd great-grandmother was Margaret Hoolihan, the youngest child of Patrick Hoolihan and Catherine Cairnen/Cairns.
She was born in Faskine in 1860, married John Gilmore in 1880 in Bothwell, and immigrated to the USA between 1882 and 1885. They remained there, had several children and Margaret died in 1941 in New Jersey.
So far I only found one other family line that came to America: Katie (Hoolihan) McNally, daughter of Margaret's brother Charles. Katie died in her early 40's in New Jersey and after her death, her son Richard McNally lived with my 2nd great grandmother.
The only other family lines that I found that left Scotland were through Mary Hoolihan, sister of Margaret and Charles. After Mary's son Patrick Conway died, his widow and children gradually immigrated to Canada.
If you have any information on Patrick and Catherine's ancestry, or where they are believed to be from in Ireland, I would be interested to hear more. All I have is Catherine's parents' names from her death certificate.
Are you on FamilyTreeDNA or GedMatch? Which line are you descended from?
Thanks!
