It's more than likely that all his loved ones had been exterminated by the Dominion.
You know how I keep saying that hogan and Janeway should have been fucking?
He started as a Maquis terrorist, made it to enlisted crewman as a given and then promoted to Ensign because he's not a fuck up, AND THEN Lieutenant in just over a year... Either this kid was EXCEPTIONAL... Or he was sleeping with Janeway.
Wardrobe screwed up.
I don't care.
Canon is canon.
