Corvus Lestrange Jr (aka Corvus Lestrange V) was a French wizard and a member of the pure-blood Lestrange family. He was the son of Corvus Lestrange and Clarisse Tremblay (CGf). He died as an infant when the ship carrying him and his half-sister, Leta, to America sank in the Atlantic Ocean. Leta Lestrange swapped Corvus with another child because she said she didn’t want to hear him cry anymore (CG)
"Corvus" is Latin for "raven" and the family name (Corvidae) of black birds including crows, ravens, rooks and jackdaws.
