from DAVID - A biblical name that was adopted by early Welsh Chrisitians. It is poular because the Patron Saint of Wales is named Dewi or David. The Latin version is Davidus, which led to the Welsh Dewydd and Dewi. However, Dafydd is more widely used. The use of this surname is mostly concentrated in Carmarthenshire, South Cardiganshire, North Pembrokeshire, and the Vale of Galmorgan. Varients are DAVIES, DAI, DEI, DYAS, DYOS, Dew, DAKIN, DAYKYN, DEAKYN, DACKINS, DAVIS and DYKINS.
