I don't know that the terms have any usefulness or utility. Bastard has taken a new meaning in the language, and indeed there are a few of them around--many of them elected. I saw two dogs get "wedlocked"--more like gridlocked. One of them was a female shepherd that 'belonged' to me (I can hear the remarks from here--knock it off, SVP), and the male that had got himself into the situation seemed to want to get himself out of it (both the situation and the female). Buckets of water didn't work. As to illegitimacy, I don't really know what that means. I can't perceive ANY child as illegitimate.
