2264 Sabrina           Discovered 1979 Dec. 16 by E. Bowell at the Anderson Mesa Station of the Lowell Observatory.
Named for a legendary English princess, daughter of King Locrine. Along with her mother, Sabrina was drowned in the River Severn by Locrine's angry widow. Sabrina became the Roman name for the River Severn.
