I have a comment on the whole first-cousin issue. I know two first cousins who actually got married. Their parents were very upset about it, so they called Church headquarters to see what the Church's stance is. They were told that the Church has no official objection and a first-cousin couple can get married in the temple, as long as first-cousin marriage is legal in whatever state that couple gets married in. Moral of the story: the couple I know went to Alaska to get married because first-cousin marriage is legal there and there is also a temple. Go figure.
