Some of the most famous names in history came in pairs, or threes, or fives. This sibling trivia round is about brothers and sisters who shared the spotlight: aviation pioneers, tennis champions, boy bands, film directors, comedians, novelists, athletes and a few notorious twins.

It mixes music, film, sport, history and literature, so it works for a family game night or as a themed round at a pub quiz, and it is easy to adapt into a 'which sibling?' rapid-fire game. Every answer is checked against a reference page, and each explanation adds one more thing about the family in question.
