From an English surname which was derived from the name of a Norman town Perci, which was itself perhaps derived from a Gaulish given name which was Latinized as Persius. The surname was borne by a noble English family, and it first used as a given name in their honour. A famous bearer was Percy Bysshe Shelley (1792-1822), an English romantic poet whose works include 'Adonais' and 'Ozymandias'. This name can also be used as a short form of Percival.
