Hi I just saw your posting maybe this might help. I am also a descendant of Sion R. Bostick. He was my third great grandfather. In one of my searches I to found the name Caleb Bostick the name was listed in one of the books about early citizens of Texas. However, all of the other articles list Levi Bostick as being his father and I have researching for many years. I think that the article just listed it wrong. It also lists that his first wife Susan died then he remarried which is also inaccurate because they really divorced in 1856.
