I may as well jump in here too.
My log in is not my birth name. I was born David Goldsborough, my birth parents were young teens, and I was placed in the orphanage. adopted and renamed Steve Sells later.
I am a proud member of a group that assists adoptees in getting medical information, who in case you don't know are 2nd rate citizens in the US, and in many cases are not allowed medical nor ancestry histories, and many provided at adoption are Illegally faked, mine was.
Through my helping others I found a lead to the agency that delt with my adoption placement, as well as a small snippet of a law change in Michigan where I was born that allowed updated medical info, 6 months later I was on the phone talking to my Birth Mother.
There are registries where people can place their names to make known their desire to make contact, when a match is found, they can talk to an Intermediary, (just in case) and my Birth mother stated she wanted to talk to me.
so with Birth Mother (known 7 years now), Birth Dad (never met but have info), and the family I grew up with, I have 1 brother, and 7 sisters, thats a lot of Xmas cards. also I am Steve Sells, I just didn't start out that way;)
