Septimus Weasley

Septimus Weasley was a pure-blood wizard who married Cedrella Black. Considered to be a blood traitor by the Black family, their marriage caused Cedrella's removal from the Black Family tree. The couple had three sons, including Arthur Weasley.

Etymology
Septimus is a name of Latin origin. It means seventh.

Behind the scenes

 * It is possible that Septimus was sorted in Gryffindor house, as Ron Weasley, his grandson, stated that all his family was sorted into Gryffindor.
 * Septimus is a Roman name meaning "seventh" in Latin. This is interesting, considering that seven is the most magically powerful number, and that Septimus Weasley's son Arthur went on to have seven children. The name "Septimus" is usually given to a seventh-born son, indicating that Septimus Weasley likely had six older brothers.
 * Bilius may be another of Septimus and Cedrella's sons; this cannot be confirmed, however, as it is only known that he was the uncle of Ron Weasley and his siblings, not whether he was born, as he is not married to, a Weasley or a Prewett.

Appearances

 * Harry Potter and the Order of the Phoenix (film)
