i'm sticking with my illegitimacy and "Yang is looking for her mother" theory.

And, that's just my preferance. Of course, it's entirely possible that as you say, Yang's mother went missing/assumed KIA etc and Yang is searching for her.

One plus year is a long enough time for anyone to get over their grief, find a new love, and have a child. We don't need marriage to be a major factor here (its significance has unfortunately diminished even in real life, and as a Hunter the idea of marriage can be very painful...).
