I was trying to research my paternal grandfather, Lewis Mark Frey b1896, and got a copy of his social security application. His parents were Rosetta Uhlfelder and Mark Lewis Frey of NY, NY. I believe he was born in Rhode Island however. I'm now trying to find info. on both Great Grandparents.I think they were in show business (Vaudeville) and may not have been married.Curious about Jewish origins of the Uhlfelder name etc.
