Other

 * The Peverell family died out long before Harry Potter's time, but some of their descendents include the Potters and the Gaunts.
 * Dolores Umbridge mentions the Selwyns as an old pure-blood family when speaking to Hermione Granger disguised as Mafalda Hopkirk, and there is a Death Eater by this surname; however, Umbridge may have been lying to "bolster her own pure-blood credentials".
 * The Burke family may be a pure-blood clan, as Herbert Burke married Belvina Black. She was not disowned for this marriage, suggesting that Herbert was a pure-blood and thus acceptable to her prejudiced family. They had three children and may have been related to Caractacus Burke.
