My father was married five times before my mother who is wife #6 and the one to not end in divorce so far. All his prior marriages ended in messy, nasty divorces. My father's family always had some questions about whether he fathered any children during those marriages even if not with the actual wives at the time. It seems two of those marriages were very open and involved other men and women frequently. Which is why they have so many questions. My father played around a lot back in the day and so did the ex-wives. They wonder if a pregnancy was blamed on another man when really my father was the father. It's stuff they are so curious about.

I (24m) do not care if he has other biological children out there. Even if he does I'm not interested in having a sibling relationship with any of them. My father's family wants me to see via Ancestry/23&Me. They feel like I would have a better chance at matching with any children my father has and having them reach out.

I suggested two of my aunts, who are my father's bio siblings, submit their DNA and do the searching if they want. I told them I had zero interest in finding siblings and having a relationship with them. They couldn't really understand that and said as much. I told them they didn't need to and that got their backs up a bit. They told me I could have family out there, could have a sibling to have alongside me for the rest of my life. They talked about how close they all are (including with my father) and how I could have that. I told them I didn't want or need it.

They said they'd give me some time to think it over but my answer has remained unchanged. My father doesn't believe he has more kids out there. That's why they won't get him to do it. But I still don't want to know and even if I did it for them it could mean a potential half sibling would want to know me and might not take it well that they matched with a sibling and instead got aunts and uncles and not the sibling. My aunts and uncles said this wasn't such a big deal and if they find some maybe I'd change my mind anyway.

AITA?
