Mr Prewett was an English pure-blood wizard and a member of the Prewett family.


He was the brother of Ignatius Prewett.[2] the husband of Mrs Prewett, and the father of Molly Weasley née Prewett, and Fabian and Gideon Prewett. He was the maternal grandfather of the Weasley children. He was also the father-in-law of Arthur Weasley. He could also possibly be the nephew of Muriel.

He may have owned a Wizard's Chess set[3] and may also have had a big nose.[4]


Notes and references

  1. Molly's Ministry file — seen here — states that red hair is a family trait for HER family, so she inherited it from one (or both) of her parents, meaning that Mr Prewett may have had red hair.
  2. Sirius Black stated in Ch. 6 of Harry Potter and the 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 [false logic: this merely means that Lucretia Black Prewett (Ignatius' wife) could not have been their mother]. 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.
  3. Harry Potter and the Philosopher's Stone, Chapter 12 (The Mirror of Erised): Ron's chess set is stated as belonging to his grandfather, but it does not say whether it was his maternal grandfather or his paternal grandfather.
  4. Harry Potter and the Prisoner of Azkaban (script): Fred states that George's nose looks "positively massive" and is corrected that it is his - he says it is a family trait from Molly, implying that one of Molly's parents had a big nose too, though it is unknown as to which parents did.
