Family Branch
Doing something like Ancestry.com or 23 and Me can be a real eye-opening experience. You can learn a lot about your family tree and even get important health information from your genes. Unfortunately, this user doesn’t have any need for this service because their tree is a simple branch!

Honestly, it’s quite baffling to see how many similar cases to this have happened on this list. At least the user recognizes the problems of doing such a thing – let’s just hope that everyone in this family is safe and well. I also strongly recommended dating outside of the gene pool.
