Mens names for a book?

I've always liked Jack for an upper class gentleman but sense the brother is Johnathan I would go for Michael or Maxwell. As for the mom I wouldn't do Elizabeth, it's been so over used as for Charles. Something like Jenine or Catherine for the mom. I can't think a good one for the dad. What I've done for my books is look at peoples names around you (family and friends) and strangers. The best thing I've done to think of names was grabbing the phone book and flipping to random pages, it helps. Wish you luck in your writings.
