Of the 3 tests on my account, my sister's is the only one with a "new" relative. It's so incredibly wrong that I don't know what to think. 3 of the 4 people in her new circle are already in a circle for another common ancestor. The 4th person has an ancestor that is very likely to be a close relative of that other common ancestor. But because the 4 people share a completely different pair of common ancestors, Ancestry has put my sister into a circle for an ancestor that is in no way related to her.
Oh, and those awful biographies are back.
