I don't know if there is a family tie-in here or not, but my ancestors include John McMaster, born between 1830 and 1835 in County Tyrone, who emigrated to the U.S. around 1853 and settled in Lee County, Illinois. He had a brother named Oliver McMaster who also came to the U.S. and maybe a sister named Elizabeth. I don't know his father's name, but family legend is that he was some sort of a lay preacher in the Catholic Church.
