Susan according to wikitree relatationship finder I am related to all you have listed. I have possible direct relationships to 4 or 5 siblings in one family according to the relationship finder. In the Anjou line and multiple direct line in siblings in Plantagenets. For 4 generations. It could happen, maybe? I doubt it. But it would take me more than one life time to prove it. I would be willing to bet that many members on wikitree would find the same thing if they went to the profile of the first Count de Anjou and used the relationship finder on every person listed on profiles from there down. While I find it great fun, I'm with Andrew I take it all with a grain of salt. Thanks for the info.
