Licorus Black

Mr. Black was a pure-blood wizard. He was an early member of the House of Black. He married a pure-blooded witch and he is the earliest known ancestor of the Black family. It's possible that Alexia Walkin, Phoebe and Eduardus Limmete were his siblings.

Behind the scenes

 * This character appears only on the version of the family tree shown in the film adaptation of Harry Potter and the Order of the Phoenix. He is decipted on the tree as a man in a green hat, very much like Pollux Black. He is decipted on the begining of the tree, and on the same branch is decipted Mrs. Blishwick, so it is possible that she was his daughter.
 * This character is decipted as the first Black, but we know that he isn't really the first Black, because Kreacher, the house-elf, said that family tree tapestry exist seven centuries. So, it is possible that this wizard was the first decipted Black, but he wasn't the first Black in the history of family.
