As one of the players in that game (or at least in one of the games where it came up) I agree with Redoubter (though, to be clear, I was also the one who had Foreign Wives in battle). Fortunately, it did not end up affecting the outcome of the game (well, maybe slightly, but not significantly). I was playing another Elder, who believed differently, and the host ruled in his favor. I had no issue with how it was handled.
