"My dad was 15 and my mom 21 and married at the time," said Mayer.
Adopted by her current family at the age of four, 23-year-old Jessica started looking for her father online nearly 10 years ago. But it wasn't until a mutual acquaintance pointed out his profile on Facebook that she found him. The only catch was that Rozell was living in the United Kingdom, so she messaged him.
"I never knew anything about myself and I thought he was going to say, 'I gave you up, for a reason, let's leave it that way,'" said Mayer.
As it turns out, her fears were completely unfounded. And they soon arranged their first transatlantic Skype call, which is how ABC7 spoke to Rozell.
"I always dreamed of what my girl would be...she has exceeded every expectation I ever had," he told ABC7. "In some ways it hasn't set in...until I can hold my daughter in my arms."
That meeting will happen next month when Jessica will fly to Wales to meet her dad and the one-year-old half brother she now has. But as excited as she is, Jessica is also quick to point out that Rozell will never erase the love of the parents that raised her.
"I'm a lot more confident and self-assured in myself I think than I ever was to know who he is...my biological dad is not a replacement, he's an addition. So I now have two dads that are vastly different that love me in different ways," she said.
