Hello,
I have a susan/(nah) Darcy married to a francis fitzpatrick. Having trouble locating in Ireland, however Susan(Nah) Darcy seems an unusual name in Ireland, although I believe there are some in Leitrim from my searches. Does it ring any bells with you? This couple have a son, patrick ~1821 who then emigrates to Scotland. I believe Susannah and Francis are probably Catholic.
Any help appreciated,
Fi
