What are the names of Roger Federer's twin daughters?

Roger Federer’s twin daughters are named Myla and Charlene.

The girls were born in July 2009 to Federer and his wife, Mirka Federer, a former professional tennis player. They are identical twins. Their names are also sometimes reported with fuller forms—Myla Rose and Charlene Riva—but “Myla and Charlene” is the standard concise answer used in general biographies and trivia.

The couple married on 11 April 2009 at Wenkenhof Villa in Riehen, near Basel, Switzerland. Their daughters arrived only a few months later, beginning a family story that would include another set of twins.

In 2014, Roger and Mirka welcomed fraternal twin boys, Leo and Lenny. That unusual family detail often causes the main mix-up: Myla and Charlene are the daughters, while Leo and Lenny are their younger twin brothers. Federer has generally kept his children’s lives private while occasionally mentioning family life during interviews and public appearances.
