Researching the family of my GGGGGrandfather Thomas Erwin/Irwin, born in Ireland abt. 1775-80. Sorry I don't know what part of Ireland he was from! Married in 1797 in Kentucky then went to Ohio and was a successful farmer, owning a great deal of land in Champaign and Hardin Co.'s. Had 3 sons, William, Robert and Thompson. All were church elders and township trustees, very involved in their community. Shari Adams Cygan
