Thanks for the clarification. After some googling, I see apartment house is another term for apartment building. . . So if you live in an apartment, you live in a "house". Haven't done the puzzle yet so not sure how relevant that is but it would explain the perceived discrepancy. It was noted that this was published in 1959. I'm sure reality hasn't changed since then in terms of children and bachelors but I'm wondering if there were some different assumptions back then about recognizing children outside of marriage. I get the feeling that unless you're a politician, it might not be quite as big of a deal for a bachelor (or bachelorette) to have a child now as it was in the 50s. I don't have any evidence of that though.
How does recognizing divorce contradict engaged men being bachelors? Google shows a bachelor as being a man who isn't and has never been married. So an engaged man would be a bachelor because he's not actually married, a divorced man would not be a bachelor because he used to be married, but as written, it doesn't matter anyway because Green is still married until the suit is settled.
