I don’t really know where to start, but I need to get this off my chest because it’s been messing with my head in ways I didn’t expect.
A few years ago, I took a 23andMe test just for fun. I wasn’t looking for anything dramatic—just wanted to see if I had some random ancestry or health info, maybe find a few distant relatives at the most.
Then a few months ago, a notification popped up…”new possible relative connections”, and I was expecting some twice removed cousin or something of the sort.
But there it was:
Half-sister detected.
At first, I assumed it was a glitch. Or maybe a cousin mislabeled? But our DNA results showed 50% shared .She was just as stunned as I was. Her whole life, she believed the man who raised her was her biological father. But she’d always felt like the odd one out—she looked different than her siblings and never quite understood why.
Still, she never questioned it seriously. Until she took her own DNA test out of curiosity. And suddenly I popped up. Half-sibling. No shared mom. That only left one option.
I decided to message our biological father—he was not a part in either of our lives, but I had recently opened communication with him. I wasn’t even sure how to ask. I just sent her mom’s name and asked if it rang a bell.
The pause was long. He was freaking out, and then he said something like, “You’re not going to believe this.”
Here’s what he told me:
Years ago, he owned a martial arts school. One of his students was her brother, and their mom had a one-night stand with our sperm donor during a break in her relationship,. Nothing serious. They didn’t keep in touch.
A week later, she got back together with her boyfriend, (whom later became her husband) . Not long after, she found out she was pregnant. And she never told anyone what had happened. Her husband raised the baby as his own, and she took that secret with her to the grave. My now half sister eventually told her dad, who said he always had a lingering feeling, but it didn’t change that she’s always going to be his daughter.
So now I have another sister. A whole human being I never knew existed, and it just feels like something out of a sitcom, not my actual life.

Good story, chat gpt
This is actually a nice ending to the story. So glad her dad still accepted her as his own. I always hate, although somewhat understand their anger, how someone can just walk away from a child/someone they raised because there isn’t a blood relation. Want to be angry at someone, it should the other person. It’s not the child’s fault.
Glad you found a new sibling!
50% shared DNA for a half sibling? Funny, 23andMe says half siblings would be around 25% shared DNA. Full siblings are approximately 50%. So your results are either fucked or this story is fake.
Sauce.

This is such a low effort story.
And lately reddit is just laser focused on 23andMe stories of family trees blown open by found half siblings
I got two siblings from 23andme. It’s all about the people you were raised with at the end of day tbh 🤣
Im adopted and did 23&me to find my biological relatives. I found out I have twin half sisters who are the same age as my daughter. My biological father passed at 45, and i was 26. He never knew about me. By the time i knew about him, he was gone. I do have a good relationship with my twin sisters, tho. They are in college, doing well.
It is pretty wild how life turns out. I went from being the youngest in my adoptive family to the oldest in my biological family. I also now have 7 siblings instead of 3 now. I have 2 half brothers also on my bio moms side, but we are not in contact, and i dont think that will ever change.
dead internet theory is real
My half sister found through Ancestry results never wrote me back when I tried to get in touch…😢
Hey OP, how do you feel about most folks in this sub noticing you say that your alleged sister shares 50% DNA with you, which would make her a full sister and not a half sister?
Are you a chatgp bot?
😑
How did the sister pop up as your relative if she hadn’t taken the test yet
Wife and her siblings found out the oldest of them has a different dad.
Turns out the parents knew this, but kept it secret until 23andMe spilled the beans.
Pretty fucked up though, as that means he has been telling doctors incorrect family medical history since they hid it from him for so long.
I have a half-sister that I knew about but didn’t grow up with. I connected with her a few years ago and found out how alike we really are. So much alike that I sold my house and moved to have her always in my life.
Sometimes, these are true blessings!
My daughter found her father and her half siblings on Ancestry. They never knew that she existed until 5 years ago. One was a teen and the other is only 8 months younger than her; they’re in their 30’s. Dad apparently had to have a few very difficult conversations with his family members. Lol
If it makes you feel any better I found my half great uncle the same way. He’s my maternal grandmas half brother. They have the same dad but different mothers
