Martha (Mattie) Wilson married James Riddle(Riddell) about 1824 in Northumberland Co. PA. They had children Robert, Matha, Mary Elizabeth, Samuel Wilson, Margaret and Charles. Martha Wilson Riddle was born about 1797 she died 1 Sep 1876 and is buried in Milton Her mother Mary Wilson was born about 1780-1785 and died after the 1860 census. (the 1850 census says 1785, but that would be pretty impossible because of her daughters birth about 1797) Searching for the husband of Mary Wilson. Since one of Mary's grandsons was named Samuel Wilson Riddle, that is the only lead I have. Can't find where Mary Wilson is buried either. Thanks janet welty
