Let's just say, even if true, this isn't very surprising.
The genealogists had to go back to the 1300s to find a common ancestor. (John of Gaunt, son of Edward III)
I believe I am 11th cousins, or closer, with, among others:
- Franklin Delano Roosevelt
- Ulysses Simpson Grant
- George Romney (and his son, Mitt Romney)
- John Kerry
- Anthony Perkins
- Cary Elwes
- Ann Bradford Davis
- Clint Eastwood
- Shirley Temple
- Debbie Reynolds (and her daughter, Carrie Fisher)
- Patrick Swayze
- William Holden
- Viggio Peter Mortensen, Jr.
- Ashley Judd
- Fred Rogers
- Lillian Gish
- Hart Crane
- Oliver Wendell Holmes
- Orson Scott Card
- Alfred Kinsey
I am happier about the relationship with certain individuals above than I am others.
Note: All of the above, and I, allegedly share a common ancestor, Thomas Stoughton (1557-1620)
If someone can trace their ancestry back to 17th century New England, it is very likely one can find similar relatives to the ones I listed. Maybe not the same ones, but similar ones.
There was a website that claimed Geoffrey Chaucer was my 18th Great Grandfather. They were almost definitely wrong. Lots of genealogical information on the internet is wrong. (I might be descended from William de la Pole, 1st Duke of Suffolk, who married Chaucer's granddaughter, but the descent would be through his illegitimate offspring. However, there are other problems with the alleged descent.) I am confident I trace my ancestry back to the Stoughtons. I am not confident that all of the famous people listed above can do so. But others claim to have done the research. (Note: I am most confident about Patrick Swayze, since I have Swayze ancestors, as well. We're 7th cousins.)
