Fictional Character Appearing in the Harry Potter Book Series:

DO NOT merge with real people or into the "big tree"

"...Marius Black was a Squib, the third eldest child of Cygnus Black II and Violetta Bulstrode, and brother of Pollux Black, Cassiopeia Black, and Dorea Black. Marius was disowned and removed from the Black family tree tapestry for being a Squib[1], as his family believed strongly in the importance of blood purity and disdained Squibs, who are generally treated as second-class citizens in the Wizarding world[2]. Marius's date of birth is unknown, but given when his siblings were born, Marius was likely born between 1915 and 1920..."
