Dewey: Name Meaning, Origin, Popularity, & Inspiration

Boy name origins & meanings

Welsh : from the personal name Dewi, Welsh form of David.
Anglicized form of a French Huguenot name of uncertain form and origin. Traditionally it is recorded as Douai, from a place in northern France, but it could also be from Old Norman French du we(z) ‘of the ford’, from a variant of standard French gué ‘ford’.
Thomas Duee of Sandwich, Kent, England, emigrated to Dorchester, MA, in 1634, where his name is recorded as Dewey. Another line is apparently descended from a Huguenot family called Douai, who settled in Kent, England, in the latter half of the 16th century. The connection, if any, between the two Kentish families is not clear.
