Interesting connections--like a triple cousin
I have been researching my anestors, and their cousins, for many years.
I have become interested in the tangle of pedigrees created when three sisters of the Smith family marry 3 brothers of the Johnson family.I ponder the relationships of the descendants---certainly they were double cousins, at least. I wonder if any other researchers have noted similar pedigree tangles in their respective areas of investigation?
In the family of President Bush I have seen documentation that Flora Sheldon was a fifth cousin to the man she married (Bush).I wonder if this fact was known at the time?
Has anyone ever established a triple cousin relationship?
