Antonita "Tonita" Roybal

San Ildefonso potter. She and Maria Martinez and Desidera, her cousins, were taught how to make pottery, by Tonita's mother, Dominguita Peña Montoya.

One of the finest of the San Ildefonso potters; her work is considered to be as fine as Maria Martinez's pottery; also, she both created and painted her pots.  (This is unusual; the work is usually divided between artists.)
