Per your request, I believe the following is true: He came to San Antonio from Kentucky, was a judge during his life, his middle name was Williams, was grandfather to 5 time S.A. Mayor Walter McAllister, was one of my maternal great-great-grandfathers. One of my maternal grandfathers also bore the name Samuel Williams McAllister(died about 1950) as did my mother's brother(died about 1943 at Solomon Islands, Betio, Tarawa Atoll,USMC, WWII). My oldest of two living younger brothers also bears the name of Samuel Williams Weaver which apparently goes back to the original Samuel Williams Mcallister's family influence (I wonder about the origin of the Williams Portion). My mother's maiden name was Jacqueline McAllister born in S.A. October 1923. Her paternal grandmother was Sophie Santleben who married Edward McAllister(I believe a son to your requested Samuel McAllister). I don't know much about the rest of the tree, but I surely would Like to.
