I am helping my mother in law out with her tree. She has a family tree written 1840's-1850's time period. The names are the same. There is a line written:
William Fitzgerald and Charlott Finn, both Natives of Count Kerry, Ireland married in 1852 and emigrated to Canada in 1848. There are other Fitzgerald's listed with birthdates in the1850's. Other family names in her tree are Kelly, Crawford, Kavanagh and of course Fitzgerald. Please let me know if this connects to anyone as she as a large amount of history that might help.
