Let's put this in simple terms: If Bob and Bill Jacks were brothers and they each marry sisters, Jana and Jill Johnson, how would I go about organizing it? If I add that Jana is married to Bill, but want to add that Jill is married to Bill, then how would I set that Jana and Jill are siblings? or vice versa, If I set Jana married to Bill, and add that Jill is Jana's sister, how would I put Bob and Bill as siblings? This would apply to any type of interaction between two or more familymembers with two or more of another family....
Another question, if Bob is married to Jana, and Jana dies, and Bob marries Jill, how would I set that Jana and Jill are siblings? I'm sorry if this is obvious, but this is crucial in extending my family tree, as two brothers from one side married two sisters from the other.
