ASOIAF Name Generator

George R. R. Martin builds Westerosi names by taking familiar English and Anglo-Norman names and bending one letter: Eddard for Edward, Catelyn for Catherine, Jaime for James, Petyr for Peter, Robb for Rob, Margaery for Margery. Surnames belong to houses, and each region has a signature sound. Northern houses are blunt and Anglo-Saxon (Stark, Umber, Karstark, Glover, Cerwyn); the Reach is softer and floral (Tyrell, Redwyne, Fossoway, Rowan); Dorne is Rhoynish-inflected with a Spanish lilt (Martell, Dayne, Yronwood, Uller); the Ironborn are salt-hard (Greyjoy, Harlaw, Drumm, Blacktyde); and Valyrian bloodlines chain long vowels together (Daenerys, Rhaenys, Aegon, Velaryon, Celtigar).

Bastards take a regional surname instead of a house: Snow in the North, Rivers in the Riverlands, Hill in the Westerlands, Flowers in the Reach, Sand in Dorne, Storm in the Stormlands, Waters in the Crownlands, Pyke on the Iron Islands, and Stone in the Vale. Essos has its own systems: Ghiscari masters use "mo" or "zo" between names (Kraznys mo Nakloz, Hizdahr zo Loraq), Braavosi and Volantene names sound Italianate (Tycho Nestoris, Malaquo Maegyr), and Dothraki names are short and guttural (Drogo, Jhogo, Qotho).

The list mixes canon characters with new names built region by region, so a Northern bannerman, Dornish bastard, or Braavosi banker sits naturally beside the books.
