DNA testing reveals mystery half-sibling

Dear Amy: I was curious about my DNA history, so I purchased a kit from one of the major testers. The results came back, indicating that I have a half-sibling. This half-sibling then contacted me and said he never knew his dad because his mom was artificially inseminated from an anonymous sperm donation.

I asked my parents if it was possible for me to have a half-sibling and they both said no.

Regardless of the truth, I can honestly say it isn’t going to change my view of my parents(I love them dearly). I’m mostly just curious now and feel a bit obligated to help my potential half-sibling learn about his family (if it is true we are related). Your thoughts about this? — Confused Brother

Dear Confused: You should speak with your father privately. Tell him that two tests have confirmed this DNA connection, and that you believe the results. Assure him that you love him, and that you know he’s done nothing wrong. In fact, this donation enabled a stranger to start a family. Offer to help in communicating with your mother, if he wants.

If your father continues to deny this paternity, there is nothing you can do about it. As an anonymous donor, he has the right to try to remain that way. Don’t push.

Yes, if you want to, you should contact this half-sibling and offer to share family photos and some basic health information with him.

You will also have to decide to what extent you want to be involved with your half-sibling.

It will help to think of this experience as a process you’ll encounter in stages. You will all make a series of choices which will lead you to encounter unknown challenges. With advanced DNA testing, this sort of situation is becoming much more common. Resolve to handle it with integrity.
