Early Bio and Parents

Thaddea Graham was born in China on 29 March 1997. Her adoptive parents adopted her from an orphanage in Changsha, China, when she was very young.

Graham’s parents are of Northern Irish descent. She spent most years of her childhood living with them in Ireland. Growing up, she was passionate about music and loved doing creative things. 

Talking about her parents in an April 2021 interview with Grumpy Magazine, she said, “I don’t see my story as the fact that I was abandoned. I think [my biological parents] did it with the intention that they would give me a second chance at life, and I don’t want to disregard the incredible decision my parents made to adopt. So many people have opened doors for me and I don’t want to waste that.” 

She did not have any thoughts of pursuing a career in acting. However, her mother later suggested enrolling in a drama school in the United Kingdom.

Taking her mother’s advice, she attended the Arts Educational School in London and later graduated with a fine arts bachelor’s degree. 

While there, she performed in several stage plays and acts. Moreover, during the play titled People, Places, and Things, she realized she was meant for acting.

Graham portrays the character Bea, the leader of a teenage group. According to her, Bea is a headstrong and confident 17 years old girl who leads the street gang in the series.

“I really loved that Bea’s driving force is her little sister, her relationship with Jessie,” Graham said of her character in a 2021 interaction with Observer. “Having that really strong female relationship where it’s nothing to do with romance is great. It’s love, but it’s a different kind of love, and I think that is really at the forefront of it.
