An ancestor of his is a part of the Texas/Mexico history books, was a governor of a Mexican state, lost an arm fighting Santa Anna, and was run out of Texas after the Alamo for having held supplies back at Goliad instead of taking them to the Alamo. The families land was subsequently stolen (would have been much more than the King ranch) and was subject of a several hundred million dollar lawsuit in the 80's (dropped - I think the jurisdiction? thing made it impossible, at any rate, they couldn't take it to the supreme court level for lack of money to continue fighting).
I know a member of his extended family. A witness.
