The biggest blessing.

Former Bachelorette Ali Fedotowsky Manno just shared how she “didn’t even know” she had a sister until recently and the “crazy” story of how they met.

The Bachelor Nation star took to Instagram to share a series of photos with her half-sister Tonya and their families together.

Alongside the photos, Ali wrote, “The story of my sister. We had the absolute best few days with my sister Tonya, her husband Sonny, and my two nephews. All people that I didn’t even know existed just one year ago. So many of you asked me how we found each other so I wanted to give you the story.”

Ali shared how they first got connected, saying, “Essentially, I wanted to learn more about my grandma Molly. My daughter Molly is named after her and she meant so much to me so I decided to do a DNA test to learn more about her. I was not looking for a family member because I assumed I knew all my immediate family members.”

She went on, “In fact, I was so focused on learning about my grandma that I didn’t even notice that in my results a person popped up under ‘Close relative.’ I think maybe I saw it one day later thinking she must’ve been a first cousin and I was super busy with two very young kids so I told myself I’d come back to it and just forgot.”

The former Bachelorette explained, “Well it turns out that Tonya had also taken a DNA test and she got alerted to the fact that she matched with me. She opened it up and read that a close relative meant that I was her grandma, aunt, or half sibling. It was pretty clear that I wasn’t her grandmother or aunt so half sibling was the only option. Crazy right?!?!”

And while Ali said this is a “very cliff notes” version of the story, she couldn’t be happier to be connected with Tonya.

Tonya originally searched Ali’s name and after seeing Ali was a former Bachelorette, Tonya decided to reach out to Ali’s dad to have a better chance of connecting.

Ali shared, “She reached out to my dad and they connected and then he connected us. It’s been the biggest blessing ever! I took the test and never looking for a sister or expecting to find one. But oh my gosh I’m so glad I did! She’s funny, laid-back, down to earth, and even if she wasn’t my sibling I’d want to be her friend. So crazy how life can change so quickly. I think I told you guys this before but I’ve always wanted a bigger family and I feel like my wish came true.”

And in the comments of her post, Ali added that, “I guess I probably should’ve added that my dad didn’t know he had another daughter before this either. And the whole family is overjoyed!”
