If you have Vintage Glamour, you could do Mr. Belvedere. That show centered more on the kids, though. I kind of thought of the parents as interchangeable. If you're okay with going back further in time, you could do Burns and Allen, a husband and wife who are both in the Comedy branch of the Entertainer career. I think of that as a family show, even though the kids are pretty much grown up. If you're okay with a single dad plot line, you could do the Rifleman; have a cowboy generation.
@IllusoryThrall , I've bookmarked that legacy and I intend to play when I've finished my current one. Looks like a lot of fun!
