I, too, am related to the Tumlinsons via Capt. Peter Tumlinson's daughter Sarah (Sally), who married Marion Davis Bell Sr.
Where did you get the story that John Jackson Tumlinson's Indian killers "cut his feet and made him walk until he died"? I have never heard this before. I had only heard that Indians killed him in 1823 near Seguin, that his traveling partner escaped but did not see him killed, and that JJT's body was never found.
