I have a Sophronia Jones in my tree also. She was born 2-15-1799 to Godfrey and Sally ? Jones . One of 13 children. Family record has Godfrey born in Vt. 2-14-1776 . A son Ira Walter Jones b. 5-5-1794 also married a Sophronia Islam in Oswego Co. N. Y.some time after 1862 (2nd. wife ) . Maybe its not such an unusual name after all .
