When Hillary Harris learned the name of her next-door neighbor, it set off some mental alarm bells, and led to an unexpected family connection.

Having been raised in a loving adoptive family as a newborn, Harris has always been curious about her biological family, but that curiosity turned into necessity when she and her husband were expecting their first child. According to CBS News, Harris put in a request to unseal her adoption records in order to ascertain her family medical history.

"That had all my health history, it had a letter from my birth mother. … It also disclosed that my birth father Wayne had passed away in 2010," Harris said. "And then it had two half-sisters, Renee and Dawn … and then right here it says Dawn Johnson of Greenwood."

The following year, Harris and her husband Lance noticed they had new neighbors, and Lance went out to meet them.

"[Lance] comes in and is like, 'Yeah, I met the neighbor. Her name's Dawn.' … 'Dawn from Greenwood?' … Lance is like, 'Yeah.' I'm like, 'You don't get it?' He's like, 'What are you talking about?'" Harris recalled. "And I pulled out all my adoption paperwork. And I said, 'Dawn. Greenwood. Sister, you know?' And he's like, 'Oh my gosh.'"

Though 19 years apart, the two sisters have been busily catching up on lost time, ecstatic to have made such an unlikely connection. "That moment when I first embraced her in the driveway … I mean, it was amazing. It was a miracle," Harris said.
