NBC Today interviewed a family who found their adopted daughter's birth mother on Facebook.
As Jessi Zachtel grew up, she found herself increasingly curious about her biological family. Once in her teens, she started searching social media sites with the help of her adoptive mom.
Unbeknownst to Jessi, her birth mother was doing the same thing.
"I figured she has to be on Facebook, she has to be on myspace," said Sharyn Padula, who gave up Jessi over a decade ago. "So I started looking through all the Jessicas and all the Jessies in New Jersey. I got so many results."
