"No one lived after he decided ter kill 'em, no one except you, an' he'd killed some of the best witches and wizards of the age — the McKinnons, the Bones, the Prewetts — you were only a baby an' you lived."
Hagrid discussing the numerous wizards murdered during the first war[src]

Prewett is the surname of a pure-blood wizarding family, and one of the Sacred Twenty-Eight. They are related to the Black, Weasley, and Macmillan families.[2] With the deaths of Fabian and Gideon in the First Wizarding War[3], the Prewett family became extinct in the male line[4], though it continues in the female line through the children of Molly Weasley.

Some members of the Prewett family would likely be labelled "blood traitors", as they were members of the Order of the Phoenix and did not believe in the ideology of blood purity. However, the attitude of the prejudiced House of Black towards the Prewetts suggests that not all members would be considered blood traitors. Lucretia Black was not disowned for marrying Ignatius Prewett,[2] implying that the Prewetts were more accepted in elite pure-blood circles than a family like the Weasleys.

Distinctive family traits include red hair[5] and large noses.[6]

It is unknown whether Molly's second cousin (a squib accountant) is a Pure-blood or not; he could have a muggle mother.

The surname Prewett is Welsh in origin. It is derived from the Middle English word prou, meaning "brave" or "valiant", and the suffix "-et", which implies smallness. Thus, it is believed to be derived from a nickname for someone small, but brave.[10]

  7. Sirius Black stated in Ch. 6 of Order of the Phoenix that Molly Weasley was his "cousin by marriage". This means that Ignatius could not have been Molly, Fabian, and Gideon's father, as this would have made them first cousins by blood of Sirius. Ignatius was Sirius's uncle by marriage, and if Molly was his niece, this could explain Sirius's comment. See this talk page for more information.
