I descend from a Richard Crystal (1803-1880) who married Elizabeth Cox in 1826, perhaps in Ohio. They had, among others, Allen I. Crystal (b. 1846) who married Elsie Harrison (1862-1946). Their son, Ralph David Crystal (1889-1954), was my grandfather. Ralph married Melvina May Groves (1893-1982) who had David Eugene Crystal (1916-1986) who married Elsa Helene Boettcher (1922- ). They had me. I don't know if Richard Crystal was related to Abraham Crystal, but I would like to trace that line of the family back further.
