A variant of Petra, Petronel is an Old Greek name meaning “stone” or “rock.” It’s thought to be a Medieval English form of the name Petronella. A character named Petronella features in Jay Williams’s modern fairytale of the same name as a character who challenges the stereotypes of traditional fairytale princesses. She vows that she’ll be the one to rescue a prince instead of being rescued herself. This name conveys a sense of strength and dependability, inspiring little Petronel to overcome rocky times in life with ease.
