I have a story to tell you which I think is funny. I had an aunt, my mother's sister who decided to find out more about their dad. She did the genology & found out that he had been born out of wedlock & raised by grandparents. Well my aunt started looking at pictures of him & thought he veey big lips which she concluded meant he might have some black blood. So she gets going with finding out more. Both my maternal grandparents were born & raised in New York City. In her research she finds out a last name so she orders a telephone directory & starts calling everyone. This was and is a popular last name so you can imagine getting a phone call from a stranger wanting to ask about their genealogy! She made several friends but was never able to find out anything else about my grandfather.
