Most households are essentially groups of friends; you have to make friends with people to become a member of the household. There are pretty strict naming conventions if you want to actually get your name approved by the Laurel King of Arms, so many names get rejected or modified. I wouldn't take it personally if I were you.

None of which means you need to resume the SCA - I haven't been to an event in years - just that these two points should probably be kept in perspective.
