Growing up in Cheshire with her parents, her siblings, Samuel and Harriet, and her extended family, Dynevor showed early signs of a budding career in showbiz. "I've always been a show-off. Whenever my grandparents came to visit, even when I was very little, I'd start jumping around – but only when people were watching. There are loads of videos of me leaping about. My sister is similar, doing little dances for everyone – she's got it in her to perform too," she told Express.
