Harry Potter Last Name Generator

The Sacred Twenty-Eight, a list of families considered truly pure-blood, includes Abbott, Avery, Black, Bulstrode, Burke, Carrow, Crouch, Fawley, Flint, Gaunt, Greengrass, Lestrange, Longbottom, Macmillan, Malfoy, Nott, Ollivander, Parkinson, Prewett, Rosier, Rowle, Selwyn, Shacklebolt, Shafiq, Slughorn, Travers, Weasley and Yaxley. The Potters and Peverells are also old wizarding families that were left off the list.

Many do. Malfoy comes from the French mal foi (bad faith), Lupin from the Latin for wolf, Dumbledore is an old Devon word for bumblebee, Voldemort means flight of death, and Slytherin, Gryffindor, Ravenclaw and Hufflepuff each echo their founder's animal or temperament. Others, like Weasley and Granger, are simply real English surnames chosen for their homely sound.

Yes. Canon surnames work if you want your character tied to a known family; the original names in this list (for example Thornquist, Pemberwick or Ravenhill) give you the same Hogwarts flavour without implying a relationship to existing characters.

Wizarding Britain is deliberately written as a society stuck a century or two behind the Muggle world, so its surnames draw on old village names, medieval trades and Anglo-Norman gentry families. That is why names like Fortescue, Marchbanks and Ogden feel right and a sleek modern surname feels wrong.
