Of course, if anyone in the family was interested, it’d probably be easy enough now to get that DNA test. You can bet if I were either the father/non-father or the child, I’d want that test done. Sad how immature adults can make life so painful for a child.
Historically, that’s why in the Jewish tradition, children take the religion of the mother who birthed them, the one they know for sure is the child’s parent.
I haven't seen him in years, although I used to see him periodically... not as a member of the family, but just because we ran in similar circles. I recall that he became somewhat successful, which is WAY more than I can say about the son who was born of a second marriage.
Harsh to say, but maybe he was better off the way things turned out.
