Believed to be the world’s first parent and child to publicly come out as transgender and transitioning, a father and daughter from Detroit have detailed their journey.

Once mother and son, Erica and Corey Maison struggled individually for years with their gender identities unaware that the other was also facing a battle of their own.

Corey, 15, first told her parents that she identified as a girl at just 11 years-old and underwent a three-year process with therapists before she started physically transitioning.

But it was not until last year that she learned that her mother also struggled with his gender identity.

Now, the pair are transitioning together as their relationship shifts from mother and son to father and daughter.

The teen who is making an effort to record her transition on Instagram with hopes raising awareness for transgender children told 60 Minutes: “I wanted to make my parents proud of who I am, but I thought that they would not like me.”

Far from it, Corey’s bravery gave Eric, formerly Erica, the courage to begin his own transition from female to male.

“The first feeling was relief, the second was terror,” he said. “Fear for what my future would hold, fear for how my family and children would, fear for what the rest of my life was going to look like.”

Despite struggling with different emotions, Eric went ahead with his transition and has since undergone a double mastectomy.

As he plans to stay together with husband Les, who fully supports his transition, Eric says he regrets not coming to terms with his gender identity earlier.
