I had a brief relationship with a woman many years ago. I learned that she was pregnant but she did not know if it was mine or another persons. She married the other guy and moved away. A few years ago she died in a motorcycle accident. I just recently learned of all this information and was able to look up the child on facebook. She looks just like my youngest daughter. The child is no longer a child and is 28 years old with 2 kids of her own. Her mother and dad divorced when she was about 12 and I do not know what kind of relationship she has with him. It is clear that she is my child. So, the question is should I let her know about the relationship I had with her mother and that I am her father or not?
