Dey History, Family Crest & Coats of Arms
The Dey surname seems to have come from a few sources: it was an occupational name for a dairy maid in some parts of England and Scotland; it was a derivation from David; and in some cases the name came from the word eye (d'eye). The same source claims that name was could have been an occupational name as in 'the deye' or 'day,' a maid, a dairy-maid.
