Not sure if this is going to be a help or not, but while looking up listings in the California Death Index at Rootsweb, I came across my Grandfather's 1/2 brother Thomas Benton Fredendall b. 12 July 1852 Wisconsin, d. 11 January 1941 (age 82) in Los Angeles, Ca.-he was the son of Abram Fredendall and his first wife Nancy Serviss.I would suspect that your T. Benton Fredendall is probably the son of this Thomas Benton Fredendall.
T.B. had two other brothers, Abe and George (don't have much on them). They called their father Abram an old fool because when he married a second time he married a woman 50 years younger than himself, Ella Leona Lull, the mother of my grandfather Edward Alexis Fredendall (b. 30 Jan 1901 Kansas).
