Wait a second, Bill has kids. Is there any interaction?

Hi, I'm just a watcher of the T.V. show so to the readers of the book I have a pergunta (or to viewers who caught something I did not).

Before Bill was turned, he had a family. Does he ever try to find his great great grandchildren?

Obviously he doesn't want to visit and say, "Hi I'm your super undead great great grandpa." But does he ever talk about it in the books?

Just curious.
