"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 —"
— The numerous wizards murdered during the first war[src]

Prewett was the surname of a pure-blood wizarding family, and one of the Sacred Twenty-Eight. They were related to the Black, Weasley, and Macmillan families,[2] and more distantly to the Delacour, Johnson and Potter families and the Muggles Granger and Evans families.

With the deaths of Fabian and Gideon in the First Wizarding War,[3] the status of the Prewett family is unknown.[1] However, it continued in the female line through the children of Molly Weasley.

Family history

Some members of the Prewett family would likely have been 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 were 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 included red hair[4] and large noses.[5]

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

Possible Relations

Wizard(s) Notes
Bilius A brother or brother-in-law of Molly Weasley née Prewett
An uncle Uncle of the Weasley children who attended Bill Weasley and Fleur Delacour's wedding in 1997, he may be a brother of Molly Weasley née Prewett or one of her brothers-in-law.
Muriel's mother May be a great-grandmother of Molly and her brothers because Muriel is their great-aunt, and so possibly sister of one of their grandparents. However, Muriel may be Molly's and her brothers great-aunt by marriage.
Muriel A great-aunt of Molly Weasley née Prewett, thus an aunt or aunt-in-law to Mr or Mrs Prewett. While Muriel is Molly's great-aunt, and thus related to the family, it is not confirmed as to whether she is a Prewett.[7]
Tessie A great-aunt of Ron Weasley and his siblings.[8] She might be an aunt of Molly's or of Arthur's. If the former is the case, then Tessie is related to the family, although it would not be certain that she was a Prewett.
J. Prewitt Possibly a relative[9]
Second cousin Squib accountant
Mafalda Molly's second cousin once removed

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]

  6. 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.
