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.

Behind the Scenes

 * 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.
 * 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 a Weasley or Prewett.
