Prewett family

Prewett is the surname of a pure-blood wizarding family. They are related to the Black, Weasley, and Macmillan families. With the deaths of Gideon and Fabian Prewett in the First Wizarding War, the Prewett family may have become extinct in the male line, though it continues in the female line through the children of Molly Weasley née Prewett.

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, implying that the Prewetts were more accepted in elite pure-blood circles than a family like the Weasleys.

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.
