    Nice chart.nnAccording to the lineage at, the first mention of Charlemagne as an ancestor is ahnenriehe number A4572120626 which is the 30th Great-grandparents level. That is disputed, apparently. The first one not in dispute is 9144275744 at the 31st Great-grandparent level.nnWhat are your sources for the royal and noble lineages? Are you using Weis, Roberts, Richardson or something else?nnCheers — Randy

      Randy, The path is linked at the end of the post. If anyone questions the reliability, you can always check, correct, and document the profile. You can see who added what, and what sources they’ve added.

        There was a glitch in the tree between William and Charlemagne and it should be corrected now. Randy, we curators use whatever scholarly research we can get our hands on. For the medieval tree, we try to consult Cawley’s Medieval Lands database, Keats Rohan, Settipani, and others and also frequently consult the discussions in the archives of the soc.gen.medieval listserv and its contributors. The closer we can get to primary sources, the happier we are. But it is definitely a work in progress, and the verification and documentation research is still in early stages. We welcome any assistance you might like to provide.

    Elvis’s middle name, Aron, is spelled this way, not Aaron.

    • Anonymous

      If you look at his Geni profile, it explains that Aron and Aaron are both used.

  • Michael

    “Being the youngest brother of the two, Prince Harry”; that should be “younger … of the two”!

  • maquis

    Not sure if this has been mentioned but, Eugenie and Beatrice are NOT Princess of York, they are Princess [name] of York. Their father is Duke of York. Likewise the Wales – Prince Charles is Prince of Wales – there is only one. William and Harry are Prince William of Wales and Prince Harry of Wales respectively. Although Prince William is now titled Duke of Cambridge.nnMaybe you don’t care? Just had to share anyway :)

    Oh, and Diana was NEVER Princess Diana – always Diana, Princess of WalesnnJust sayin’n

    My mother told me that I am related to Diana, Princess of Wales. Which is believable since my mother and her look a like in many ways.
