I'm glad these messages stay here so long as it helps new researchers like myself!
I have a Martin Cullinan, B1869 in Slaveen (near Ennis), Co.Clare, who along with his brother Thomas (B1866) moved to New York. I have no further details of them but would love to find out. Apparently Thomas might have died young (age 29?) from disease.He went to New York to find a cure.
Their parents were Patrick/Padraic Cullinan, b1790, and Ellen McKee, 1803-1908, who had 8 children.
Could we get in touch for any Clare - US connections?
