I think you're referring to Johnny Stompanato. He wasn't Lana's husband but her live in boyfriend. He was a low level mafioso, who beat the crap out of Lana on several occasions and ended up being killed by Lana's daughter. Supposedly he was quite a ladies man and there were jokes when Lana lost out on winning the Oscar for Peyton Place that at least she still had Johnny at home, commenting on the size of his endowment.
