Meaning & origin(measured from records)
Main GB Location (1881): widespread in England. occupational name from Middle English day(e), dey(e) ‘dairy maid’, sometimes ‘a woman who keeps cows and other farm stock’ (compare the 1221 example). Originally used only of women, it was later used of men with the sense ‘a man in charge of the dairy cattle’. The earliest examples below (about 1055 and about 1095) are almost certainly used in the original sense. Some of the following early bearers may alternatively belong under (2) or (3).

About this data
measured from records inferred from the name graph machine-generated
These figures come from the data snapshot of and will change as it is rebuilt.
Statistics are aggregated from the Mondonomo name corpus; related names and etymology are inferred from the name graph; pronunciation and any machine-marked transliterations are model-generated. Read how the numbers are made, including their known failure modes, and where the data comes from.
Reference works we consult — surname dictionaries, official name registers, Wikidata and Wiktionary — are named directly, beside the claims they support. The per-country source counts also include datasets of person records: we publish how many there are and their authority tier, but not their names.
