I am looking for any information about my 4x GGF who was the first O'Connor in our line to come to America. Scant information seems to put his birth year at about 1798, and was either in County Offaly, Kildare, or Armagh. He immigrated to the states around the year 1812. All other information for him is from US sources, but I'd really like to find information on his family in Ireland. If anyone has any clues, your help will be appreciated.
-reporting this in all three counties board, sorry for the repeating-
