Thanks for the clarification.
My best suggestion to you is to avoid the Family View in your Ancestry Member Tree. It is a simplistic graphic display that is not designed to handle multiple relationships.
In my own family, my maternal grandparents are 3rd cousins, husband and wife and have at least 7 other convoluted relationships because of cousins marrying and in-law relationships. I can only see those using the Relationship Calculator in FTM.
There have been numerous threads on this topic on the Member Trees and Ancestry Comments boards. When cousins marry that particular graphic will sometimes show duplicate representations of the person. Not understanding that, members have often deleted what they thought was a duplicate, only to be horrified that "both" disappeared. It is important to use the List of All People to determine if there are actual duplicates.
