The name Dewey is a boy's name of Welsh origin meaning "beloved". Dewey and discussed in our forums with posts like "Baby a Day".
From the experts:
Not heard since the 1980s, Dewey shot into the Top 20 in 1898 thanks to the popularity of Spanish-American War naval hero Admiral George Dewey. Dewey has subtle links to his Welsh roots and relation to father name David . The name was borne by the fifth century St. Dewi, patron saint of Wales. Later references include the namesake of the library Dewey Decimal System, a Donald Duck nephew, the younger brother on Malcolm in the Middle and Lemony Snicket character Dewey Denouement. It has a strong but dewy feel and is appealing enough to be ripe for a modern revival.
