For 29 years, it was assumed that my dad who raised me was not my biological father, that I was the product of an affair my mother was having. I came out with blond hair, freckles and blue eyes. A stark difference to my tanned, dark featured dad. My dad chose to raise me as his own anyways, refusing paternity tests. I was never made to feel like I wasn't his. I took 23&Me simply out of curiosity and found out that he is in fact my biological father.

ETA, since many asked-
My dad has told me he didn't want to know the results either way, but I let it slip showing my sister's the app one time at dinner. He didn't react, but I got an extra big bear hug getting on the train to leave that night.

Also ETA, because I have the best dad ever-
It was assumed when my mom found out she was pregnant that the pregnancy was the product of the affair. My features only solidified that assumption.

He was already raising my mom's first daughter as his own, who he'd met when she was 2 and told my mom he wanted to keep raising the kids together. They got married and he adopted her a few months after I was born. She was also treated so much as his that I didn't even know she was adopted by him until I was a teenager.

My parents stayed together for 14 years, and to this day are still best friends.

I found a new daughter.

Her mom moved away before she knew she was pregnant and I never knew about the daughter. The daughter thought someone else was her father. My kids got me a test a few years ago, so I was in the database. New daughter got a test kit for Christmas. She matched with me instead of old-dad. She looks like someone photoshopped my face on a woman's body. It's scary. We've gotten to know each other and talk (text) almost every day. She lives on the other side of the continent, so we've only met in person once. Her old family was horrible and she was no-contact with them, so a new family was a good thing for her. My family likes each other most of the time, so when we found out about her we thought, "Welcome to the family! The more the merrier." Everyone is happy we found each other.

They’ve always been proud of their German heritage.

My brother in law's great great grandad walked out of the woods into a colonial American settlement, a Cree warrior who had enough of his tribe and wanted to join the settlers. He founded a farm, married a girl, raised a family, often regaling the townsfolk with tales of his upbringing among the savages.

My sister bought my brother in law a 23 & Me kit for his birthday. Percent Native American DNA: Zero.

An 18th century [con] artist who got away with it for generations.

Not weird, but my best friend and I showed up as 5th cousins. We’ve been friends for over 20 years so it was hilarious and awesome when we connected and had a distant familial tie. We’re officially family now hehehe!

I have a genetic mutation that makes me less susceptible or protected from contracting kuru, or other prion diseases related to the consumption of human flesh. I also have genetic markers that make me able to run both long distances and sprint. So I feel really prepared for a zombie apocalypse.

As an adult, my father-in-law found out his mother was actually his grandmother and his older sister was his mom. Things were different in the late '30s.

Found out my cousin is actually my half sister. Growing up everyone would comment on how similar we look, also within a few months of each other age wise. Looks like my dad got with my mom and her mom around the same time. Yeesh.

Not me, but my cousin found out her father isn’t her father after taking 23andMe. My aunt is a very religious, conservative woman. Chaos ensued.

I learned that the small town I had randomly chosen to move to 10 years ago just happens to be where my ancesters settled when they immigrated to the US. I had no idea that I had relatives here or that my ancesters were from this area. I just chose this town because I liked the vibe. Apparently so did my ancesters.

Not me but my grandma got a DNA test done because she was sold as a baby and never knew her biological parents, so a family member urged her to do it so we could maybe find them. We found both sides — a half-sister from her bio mom and a half-brother from her bio dad.

Although it was kinda weird to realize we have family close by (only 20 miles away in one case), it was much weirder for the bio families to discover my grandma’s existence, since neither side had anything to do with the other.

EDIT: some more context, this happened back in the 30s (Depression Era, USA). Her bio mom and bio dad seem to have crossed paths at some point in the same city. He was a married man, she was an older teen. Not sure if it was a one night stand or something more nefarious but her bio mom was pregnant as a result of that night.

At some point in her pregnancy, she checked into a home/hospital for pregnant unwed teen mothers (using a fake name). The bio mom was told the home would find homes for the babies, so she delivered and left. Bio mom went on to marry and have her own family, while bio dad likely never knew of the situation.

As it would turn out, the home was not adopting out babies, rather selling them. Since my grandma was blonde and blue eyed she was bought quickly for a higher price to a woman looking to baby trap a guy (surprisingly it worked). My grandma didn’t know until her teens that she was sold.

That my dad is the most inbred Mormon royalty out there. I'm related to 12 of the 13 people who signed the front of the book.

The first picture of Joseph Smith was found two years ago and I SHRIEKED because he looks just like my dad 😂😭

Also my mom likes to say she's native now but she's just a racist boomer 😣.

We did a full genetic and health test on my paternal grandmother, my mom and a few of my siblings did it as well. The results showed that my grandmother has a genetic muscle composition that many elite athletes have. Didn’t believe it until Grandma broke her hip at 99, had surgery and was walking around in no time because she hated being bedridden. Even the doctor was in shock since she was so active and the surgery scar healed so well that he was second guessing if the correct hip was checked.

Turns out my sister and I also have the same genetic muscle composition. We’ve always known that some of the girls in our family were freakishly strong and naturally athletic even though we aren’t athletes. Thanks Grandma for blessing us with strong bodies 🤣.

I couldn't find any matches on my great grandpa's side and I had a weird second cousin we couldn't figure out how we were related to each other. Then she sent me her family tree documentation and there was a picture of her uncle with his very good friends and neighbours- my great grandparents!

And that's when I realized I had uncovered a massive family secret.
