English (Gloucestershire and South Wales): 1. most probably from the Norman personal name Luce (a vernacular form of Latin Lucia or Lucius). This is generally a female name, although male bearers are found in France. It was borne by a young Sicilian maiden and an aged Roman widow, both of whom were martyred under Diocletian and are venerated as saints. 2. Alternatively, the surname may be a variant of Lewis.
