Hi Cassandra, My name's James Sandefur, I was told a similar story about the spelling of my last name. It was changed from ifur, to efur by my granfather. I just started tracing my roots and on my dad's side (Sandefur) I'm not having much luck. His name was Henry M. and was born in Indiana 05/21/1911 and died in California 04/14/2001. His father's name was Harry and mother's was Lida Morris. Any info would be appreciated.
