An Etymological Dictionary of Family and Christian Names (1857)
The Celtic and Gaelic word deag or dagh signifies good, excellent, the same as Da, in Welsh. Camden supposes the name to be a contraction of David. Dai, Du, in the Welsh, signifies dark, in allusion to the complexion or color of the hair. Dhu, in Gaelic, the same, dark color, black. Deah, Anglo-Saxon, dark, obscure.
Patronymica Britannica (1860)
