I recently received my DNA results back and was very surprised to have a match of 1st -2nd cousin. My Mother had told me that I have a first cousin on my Father's side of the family but didn't have any more information. After looking at this match's tree - she is the daughter of a woman and an "unknown father". The location of her birth and the dates, along with the DNA results make it very possible that my Uncle was her Father. I have sent her a message - but she doesn't seem very interested in corresponding with me about this.
