The findmypast.com blog recently posted an article which shares how the Royal Baby is related to the children of some celebrities. This includes:

  • Children of Jennifer Garner and Ben Affleck
  • Daughter of Uma Thurman and Arpad Busson
  • Daughters of Maggie Gyllenhaal and Peter Sarsgaard
  • Son of Hilary Duff and Mike Comrie
  • Daughter of Beyoncé Knowles and Jay-Z
  • Children of Brad Pitt and Angelina Jolie
  • Children of Celine Dion and Rene Angelil

How were they able to determine the exact relationship to so many celebrities? Is the ancestry of most celebrities well known? Is there a program which can automatically calculate how my children are related to celebrities? If not, how can I calculate this on my own?

    This question seems to come close to celebrity genealogy. I think the simple answer (unless you have reason to believe otherwise) is that someone just did the research like (to some extent) you or I would.

Television programs such as WDYTYA select high-profile subjects who might be described by some as celebrities. In the course of their investigations into the history of that person, they (often) refer to a link to other "famous" people such as US presidents or UK royalty.

I believe that the program that involved Maggie Gyllenhall made a claim of a link to Edward III that would be sufficient to calculate a cousin claim of the type you describe. I imagine that there is sufficient information in many gossip magazines regarding other people in your list.

The quality of the supporting evidence is another matter entirely.
