William Jefferson Tiffin is my 2nd. consin, twice removed and the only thing that I know about him is that he had a son C.C. Tiffin, M.D. who lived in California and made a visit to Arkansas back in the 1950s looking for Tiffin family. He met my aunt, Annie Ethel Arkansas Tiffin, and wrote her a letter (C.C. did) when he got back to California and he talked some about his father.I have that letter somewhere. Will look for it.
William Jefferson Tiffin's line is Calvin and Mary and Joseph Tiffin, born 1805, and Permelia Kincheloe, Henry Tiffin II and Mary Kincheloe (my g-g-g grandparents) and then Henry and Mary Tiffin who came over from England in 1783.
