Can't find anything about a husband or kids. One article said she worked security for V.P. Cheney...photo at link. It also says her brother who died in an auto accident in 1988 was planning on becoming a State Trooper. Down farther in the article, it says she was out to dinner with her parents when she got the call that she was being nominated for SS Director. No other family mentioned, so her personal life is a mystery.
