Steve and Mark Waugh
The scourge of bowlers everywhere, the Waugh brothers were part of the Australian team that dominated Test cricket in the 1990s and 2000s. They even both scored centuries in the same innings against England at the Oval in 2001, and a a double century apiece for New South Wales in 1990. Ian and Greg Chappell, Andy and Grant Flower, and Mushtaq and Sadiq Mohammed are other siblings to have achieved the feat in the same Test innings.
