J.K. Rowling’s daughter Jessica’s middle name is Isabel.
Jessica Isabel Rowling Arantes was born in Portugal in 1993, before Rowling became internationally famous. Her father is Portuguese television journalist Jorge Arantes. Rowling and Arantes married in 1992 and divorced in 1995.
Jessica’s name is sometimes overlooked because biographical accounts usually identify her simply as Jessica. The middle name Isabel is included in established biographical references and distinguishes her full name from the shorter form commonly used in media coverage.
Rowling later had two more children: a son, David, and a daughter, Mackenzie. The family details belong to Rowling’s biography rather than the fictional world of Harry Potter. They should also not be confused with character names from the books, where several names were inspired by historical, mythological, or family-related sources.
