This site is affiliated with familysearch.org. It will tell you if your related to various persons. Royalty, declaration signers, celebrities, etc. Goes back something like 15 generations.
https://www.relativefinder.org/#/It's very cool site.
I share a common ancestor with 42 US Presidents, 42 Declaration signers, 93 movie stars, and 30 people of European Royalty. I find it kind of odd that Winston Churchill is listed on the European Royalty list.
I downloaded the full list in pdf. format which includes a lot of LDS names, my "relationships" report is 158 pages long.
