I am having a difficult time understanding everything and quite frankly am overwhelmed with the thought of the "possible" outcome I am facing.
My parentage as far as my father is concerned is dubious and my mother refuses to help. I have ascertained that the man who I thought was my dad is not through basic blood typing. You see I am AB RHNeg. The man I thought was my father was O positive. According to blood typing it would be impossible for him to be my biological father.
Recently, on my quest to find answers my "aunt" who would be the sister of the man I thought was my dad, wanted to help me out and we both did a DNA test through Ancestry. This would be my second DNA test as I have also tested with FTDNA.
The results from Ancestry are that my "aunt" and I share 1838 centigrams over 67 DNA strands. Ancestry predicts we are close relatives..
She for sure is not my grandparent, it is unlikely she is my 1 cousin, and given the blood typing of the man I thought was my father and who was the only son, she can't be my aunt... so that leaves half sibling.
I have since uploaded both my raw DNA data to GEDmatch. She doesn't know yet that the results are in,as far as I know, I plan to call her very soon...But needed to know if I was on the right track. and if she agrees to uploading her DNA data to DNA Match would that offer definitive proof, or do I have it already?
I am still numb from this information, though totally not shocked. I just need confirmation or direction.
