Behind the scenes

It is possible that their brother was Bartemius Crouch Sr., although this is unconfirmed.

↑ On Harry Potter and the Goblet of Fire - Chapter 36 (The Parting of the Ways), Dumbledore refers to Bartemius Crouch Jr. as "the last remaining member of a pure-blood family as old as any", unless the Crouches merely became extinct in the male line, like the Blacks.
