Gavin

Gavin is a medieval English and Scottish form of Gawain, itself derived from the Welsh name Gwalchmei, composed of elements meaning hawk and May (the month) or plain, though some scholars connect it instead to the Latin Gavinus, a name of uncertain pre-Roman origin associated with a Christian martyr from Sardinia. The name was borne most famously by Sir Gawain, the nephew of King Arthur and a prominent knight in medieval Arthurian legend, which helped sustain its use throughout Britain. After falling out of fashion, it was revived strongly in Scotland during the twentieth century and has since spread widely across the English-speaking world. Related forms include Gawain and Gauvain.
