Many doing DNA tests find unknown siblings, half-siblings, or one or both parents not matching them. They may find other relatives that aren’t known to them. Unfortunately, many times there’s a family secret that was never revealed to the child. Used to be family secrets could remain hidden.
Affordable DNA testing pretty much threw that out the window. I ordered my first DNA test in 2012 where it was on sale for $99.00. Most companies today sell the kits for $99 or less. Sometimes the kits go on sale for $39 – 59.
I warn people you might find unknown relatives when I do DNA presentations. These relatives may not want anything to do with you. It’s pretty common these days as more people are doing DNA testing.
It’s not DNA related, but I found a half-uncle that had been lost to the family. His sister was born after he died and the family moved out of state when she was young. His parents never told anyone. It was only when I did a search for the name on a graving website, Find-A-Grave, I foound him. The surname isn’t that common.
