Well, enlighten me, if you don't mind. I've read through this thread and there have been a few mentions made to Armstrong already having kids. I am assuming that the kids came from someone other than Teeth Crow. Can you fill in the blanks? I'm not being facetious, I really don't know.
They separated for some reason, but not necessarily his fault. In fact there were rumours his wife was catting around, so who knows?
My point was, Only him an his wife know the truth.
