LOUISVILLE-- It's not uncommon for sisters to have similarities. 

Explaining traits they share, Jill Reverman and Kristen Cornett went over the list. Reverman started, "Amy and I are both educators, and then Kristen has kind of an education role in her job as well. We all have dark hair and green eyes." Her sister, Cornett then joined in, adding "We were all born with lots of hair, lots of dark hair. Our baby pictures are crazy. We all have these huge heads of hair. Nail biters, we've all had cases of tonsilitis pretty bad. Like way more than tonsilitis and strep throat than any normal person should have, we've all had that. Oh motion sickness. We all get motion sickness really bad."

But unlike many siblings, these sisters just met. 

Cornett explained, "I've always known that I was adopted. There was never a question about that."

But growing up what the Lexington native didn't know was that she had sisters. She didn't learn that until adulthood. "Several years after I made contact with my biological mother, another sister found her, not through the state, but she sort of did some sleuthing, that was Amy, so then our biological mother put us in touch," said Cornett. 

And from state records the two knew they also had a third sister. Cornett said, "My non-identifying information that I got from the state was that there was a sister that had been born two years before me, so I always knew that."

Her half-sister, Jill Reverman had a similar experience. The Louisville native said she learned by chance. "My child Connor, he was kind of sickly when he was born, so I reached out to Catholic Charities to get non-identifying information, see if I could find anything in there that might help him. Found that I had a half-sister and then a still-born."

However, it was a 23 and Me test that revealed her biological family is bigger than she thought. Cornett took the test a few years ago, curious about her ancestry. Reverman, also curious, took the test in December. 

"I really didn't expect anybody to pop up because no one popped up on ancestry, so I kind of assumed no one would pop up, but lo and behold when I opened it up, it said, it had her first initial, last name and then it just said the words half-sister beside it. And I just, it was like oh my gosh," remarked Reverman.

She reached out to her Cornett, and the two messaged back and forth.

"I thought this was the one half-sister that I had. Turned out that wasn't really the case. I have two half-sisters," said Reverman.

The three sisters met and became fast friends. ​Sitting by her sister's side, Cornett said "For us, and for Amy as well, it's gone as perfectly as anybody could have hoped."

Except for one thing, they are missing a sister. Cornett explained, "Turns out my birth mother has had four daughters over six years. We were all placed for adoption and into different cities around Kentucky, so I'm the second in the birth order. Jill is the baby."

They think their fourth sister might still call Kentucky home. The three sisters have learned a few details. Cornett outlined some, saying "We know she was born in Louisville, and she would have been definitely placed for adoption somewhere in Kentucky. I think it's probable that she grew up in or near Louisville. And somebody's got to know here and maybe see some similarities here."

From state records, they have been able to find out some information. Cornett added, "She was born October 16, 1972 at St. Joseph Hospital here in Louisville. And she was placed for adoption through Kentucky Baptist Board of Childcare. And that's about all we know."

They also know that finding their eldest sister could be hard simply because she's the oldest. "She was the first-born, so her records, assuming she has records and knows she's adopted would indicate that there weren't any other children, because she's the first-born. So she would have no way of knowing that we exist," said Cornett. 

The sisters aren't letting that stop them, determined to find their missing sister. With her fingers crossed, Cornett said they are "Just hoping that somebody might have a friend that they might think looks like us and has that birthday, and maybe make that connection."
