"But how Rabastan or his son, returned to England right under the noses of the ministry? How, after all Rabastan and his brother did, how can he come back?"
— Servilia Crouch showed her amazement on hearing the name Lestrange.
Rabastan Lestrange was a pure-blood wizard, brother of Rodolphus, brother-in-law of Bellatrix, son of Reinhard Lestrange and likely a Slytherin at Hogwarts. He was a Death Eater who fought in the First Wizarding War. The Lestranges were among Lord Voldemort's most loyal and trusted servants, the only ones who searched for him after his first downfall. After Voldemort's first downfall, Rabastan, Rodolphus, his wife Bellatrix and Barty Crouch Jr. participated in the torture and permanent incapacitation of Alice and Frank Longbottom and was sentenced to life imprisoned in Azkaban. Rabastan later escaped with a group of Death Eaters and fought in several battles of the Second Wizarding War, including the Battle of the Department of Mysteries, and the Battle of Hogwarts. After Lord Voldemort's final defeat, Rabastan escaped from prison just before the end of the battle, he was disowned by his older brother and fled to France where he married Charlotte Asset and had a son named Agamenon.
