I did gender studies in undergrad (the type you want to do, relatively non traditional), and my best advice is to go with a person who does the type of stuff you want to do. Traditional quantitive sociology in family stuff is going to bore you and is not going to get you the type of job you want. Yeah, people warned me too about going places just because of a person, but realistically, your main advisors are really going to be the only people you care about in the department beyond your second or third year.
Steve Epstein was at my undergrad and is now at Northwestern. He does the type of stuff you want to do and is cool, maybe check him out.
