Taking another look at this one. I have an Isaac Hart (at least that is the Americanized version) born about 1780 in Armagh. This is from The Hoosie Genealogist(State Historicl Society magazine). In it it lists his naturalization as being on Oxtober 18, 1838. It also lists his age (as best he could remember) as 56. His birthplace is listed as County Armagh. He immigrated in June 1817 from Belfast Ireland to Baltimore Maryland USA. He settledd down in Indiana and raised several children with his wife.
I have tried to find information on him or his wife (Mary Carruthers born in Ireland) before without success. Is there anyway via ther web to locate any information on such a generic search? Without the exact time, place of his birth or his parents name I think this might just be the cement wall.
