Is the Samuel Evans you are reseaching by chance related to (a brother of?) Lydia Evans who married Amariah Gossett in Highland County,Oh? They had one child that we know of, Nancy Jane Gossett, born 7 Nov 1821 in Highland County & died 16 June 1890 in Maryville, Nodaway County, Mo. She married 16 June 1839 in Highland County to John Carson Wolfer Spargur. Lydia's parents we believe to be Evan Evans & Sarah Middleton.
