Yes, 2 for certain and 2 I'm fairly certain of introducing to rpg's, and maybe more but damned if I can recall at the moment. My wife and an ex-girlfriend for certain. The two I'm less certain about were a couple of Germans I'd befriended while stationed oversea's in the Army, and while I'm uncertain about introducing them to rpg's, I'd definately introduced them to D&D (2nd edition, Advanced if it makes any difference).
