The best treatment that I have found so far on Samuel Mathews is that by Jerry Palmer on Family Tree Maker:
http://familytreemaker.genealogy.com/users/p/a/l/Jerry-M-Palmer/GENE9-0001.html in which, among other things, he demonstrates that there were two men, father and son, by this name, with the son being governor while the father represented the colony in England. That aside, my problem with the Mathews line involves his purported descent from Tobias Mathew, Archbishop of York. While there are numerous on-line pedigrees making the claim that Samuel was his son by Frances Barlow, I find nothing in DNB and other sources about Tobias himself having a son, Samuel, who survived childhood.
A second question about Samuel Mathews who d. c. 1660: he seems to have married twice, once to "the widow of Abraham iersey", then to Mary Hinton, dau. of Sir Thomas Hinton(MAGNA CHARTA vol. 6, 1945, p. 1601) and SOME PROMINENT VIRGINIA PIONEERS by Louise Pecquet du Bellet, 1907, p. 40).
Has anyone worked on this family and come to a conclusion about the actual ancestry of the Samuel Mathews who represented Virginia in England and to the identity of the younger Samuel's mother? Any help would be appreciated. Bronwen
