Karen Warner, 51, said she found out her biological mother's name a few years ago when Indiana unsealed adoption records, and the discovery came with a surprise: she had a twin brother.

"Everybody kept coming up with nothing because we didn't have a name to go by or anything," Warner told WTHR-TV. Warner said the big break came when she obtained local voting records with a list of three men who shared her birth date. The third name on the list, Mike Jackman, stood out because he was a high school classmate who she had only very recently reconnected with on Facebook. Warner said Jackman a Facebook message saying they might be twin siblings, and the pair had a DNA test performed that confirmed their connection. "It's filled a void in my life I didn't know was there," Jackman said. "There was something out there, I didn't know was there and now it's here. She's here."
