Hello: I'm always happy to hear from Davins with roots in Clifden. My theory is that all Davins from Clifden are somehow related. But the names you show don't match any of my info. If you can give me some additional info I can check a little further and see what I can find: what was your great great grandmother's first name and who did she marry; did she marry and have her children in Ireland or the US; what was her mother's name; about when was she born. I'll check and see if I can find something. You said they lived in Brooklyn - does the address 123-15th Street sound familiar? Good luck! Bill
