Brandon MacKenzie
From FEInfobase
A retired Vice-Admiral, Brandon MacKenzie was a friend of Edward Beckett's parents who took him in upon their death. A somewhat harsh and severe man with no family of his own save a distant brother, MacKenzie clearly had little idea of what to do with a young boy, and so defaulted to the only thing he knew - the military lifestyle. Beckett was brought up in a strict and military environment, and almost had no choice other than to join Starfleet like his foster-father and his parents before him. MacKenzie is now retired from Starfleet and lives in cramped New York City, occasionally giving lectures at the Academy. He is also uncle to Beckett's wife, Helen.
