They wouldn't give him the same surname as an other major characters on the series unless they plan for them to be related. Since it's unlikely that he is related to khalee and BioWare can't just make something like this and then say "Hey, It's a bit universe. Stuff happens." They siply changed his name to something more awesome ; )
