Sam Adama (Samuel) is an enforcer with the Tauron crime syndicate, Ha'la'tha. He is a family man - loyal and devoted to his husband, and his brother Joseph and his family. The most important things to him are family, his Tauron heritage and the Ha'la'tha.
When he was a child, his parents were killed in the Tauron Civil War. Afterwards he and his brother, Joseph Adama (Yoseef), immigrated to Caprica. ("Dirteaters") He is very proud of his Tauron heritage, often scorning his brother for being too Caprican.
He is gay and married to a man named Larry. His marriage is a happy one and very stable. ("Reins of a Waterfall")
He and Larry are devoted uncles to their nephew, William Adama (Willie). Willie asks them why they do not have children, and why they do not adopt an orphan like his father and Sam were. Sam says it is because of the dangerous nature of his job as Ha'la'tha enforcer ("Reins of a Waterfall")
Mars is the most important God in their home because of Sam's Tauron heritage. Larry tells Willie that the Mars idol at their home is three times the size of the others because he married a "tough guy". ("Reins of a Waterfall")
Sam tells Joseph that he, "will pray to Mars and all the gods for a swift and terrible vengeance to come to those who have torn your wife and daughter from this world." ("Pilot")
