I am the 3rd generation of adoption. My bio-mom is also adopted, but I know her name after adoption. I have DNA proof that leads me to believe my bio-grandmother is also adopted out of her family; however I do not know who that person is. I do know my bio-great grandmother and bio-great grandfather. I want to go ahead and connect myself to their trees. What is the proper way to put in my unknown bio-grandmother to wikitree? I suspect she is still living, but don't know her current name or anything.
