Corvus Lestrange was a French wizard and a member of the pure-blood Lestrange family, the fourth in his line with the name Corvus. He seduced and abducted Laurena Kama with an Imperious Curse and had a daughter with her, Leta Lestrange. When Laurena died, he married again and had a son with her, Corvus (CG)
Yusuf Kama, son of Laurena Kama and Mustafa Kama, swore an Unbreakable Vow to kill young Corvus and end the Lestrange lineage as revenge for the abduction of his mother. He mistakenly believed Credence Barebone to be Corvus Lestrange (along with many others), as he was unaware that a young Leta had switched Corvus in his crib, supposedly with Aurelius Dumbledore, and attempted to complete his vow by killing Credence (CG).
Commentary
Etymology
"Corvus" is Latin for "raven" and the family name (Corvidae) of black birds including crows, ravens, rooks and jackdaws.
