Dear Amy: Over 35 years ago, when my husband was 19, he had sexual relations on two occasions with an older lady, who later informed him that he was the father of her two children. His paternity was never proven, as she was known to be dating others. I met my husband a few years later. We immigrated to this country after our marriage. We have been married for many years and have children in their 20s.

One child recently did a DNA test, which did not show any link to any possible siblings elsewhere. However, am I correct in understanding that this link would only show up if the possible siblings also did the DNA test?

I am concerned that at some point in the future, our children may find out that they do have half-siblings and will be shocked and maybe angry that they were never told.

Should my husband inform them of the possibility of half-siblings or wait to see if anything comes out of these DNA tests down the road? — Wondering Wife

Dear Wondering: This story isn’t quite holding together for me (are these children twins, or did these encounters happen over the course of a couple of years?), and so I am trying to imagine the conversation your husband might have with the kids: “When I was 19 I had sex two times with a woman who claimed I fathered both of her children, but I don’t think I did .... Sooooo, just giving you a heads up!”

I can’t imagine what you might expect your kids to do with this incomplete and ambiguous information.

A more judicious course might be for your husband to at least attempt to follow through regarding his own DNA questions and these possible offspring or to finally settle into his certitude that they are not related to him.

He might be extremely resistant to exploring a possible connection to them, but I think it is wise for you both to grasp the fact that this question seems to have dangled over your entire marriage.

You are correct that any DNA matches need to be included in the collection data, but at the rate testing seems to be increasing worldwide, matches down the line are always possible.
