I have an Anthony Bowsher, born 1799 in Northumberland County (probably), Pennsylvania, married on 04 August 1819 in Circleville, Pickaway County, Ohio to a Catherine Haley, born Bet. 1795 - 1803.
They were the parents of Rose Ann, Melekiah, Catharine, Elizabeth, Jeremiah, Olive and Thomas.
Do you think your Catherine Staley and my Catherine Haley are the same person? If so, I can give you lots of information on the Bowsher side of the family, though I have nothing on Catherine's parents.
