I have two branches of my family that have nearly identical stories about being descended from royalty. The story goes like this: The daughter of the Earl or other member of nobility fell in love with a commoner, they married against the family's wishes, and she was disinherited as a result. The couple ended up emigrating to the US to escape the noteriety. To me, both stories sound fishy - the "disinherited" story conveniently explains why the woman has no money from or contact with her "royal" family, and the fact that they emigrated to the US would have made the story nearly impossible to cross-check in those days (early 19th century). I guess I'm skeptical partly because I have debunked at least one other family story from yet another branch concerning a prominent memorial that one of my ancestors claimed to have constructed.
One of my distant relatives did research the "royalty" story from his branch of the family, and concluded that she (my g-g-g-grandmother) could not have been descended from who she said she was, but may have been related to other royalty, but can't be confirmed
Anybody else have this type of story handed down through the generations? Maybe some day when we are all in a huge DNA database, all these questions will be easily answered, but not today!
