A friend wanted me to download the app, "We're Related," which is from Ancestry. I do have an account there and the resources there have been invaluable. But this app has connected me to quite a few famous people (and my friend also) through some very bogus (or at least unproven) family trees. Some of the connections are authentic, but many are not, just like here at Wikitree!
Wikitree says that Benedict and I are 17th cousins, but the relationships are faulty. It simply isn't true. There is no proven father for Peter Coffin.
You have to do your own research and verify each relationship.
