Maria Martinez had given up her daughter for adoption when she got pregnant as a teenager.
"I thought about her a lot - birthdays come around, holidays – she was never far from my heart," said Martinez.
"Everywhere I go I'm wondering - 'OK, is this her passing me by?'" said Hall. "I've always wondered if I looked like her, if my kids look like her."
Both women were surprised to learn they had lived only about an hour's drive apart for so many years.
