Last name origins & meanings:
- English: from a pet form of David.
- English: from the
Middle English personal name Day(e) or Dey(e), Old
English Dæi, apparently from Old English dæg
‘day’, perhaps a short form of Old English personal names such as
Dægberht and Dægmund. Reaney, however, points to
the Middle English word day(e), dey(e) ‘dairy maid’,
‘(female) servant’ (from Old English dǣge, cognate with Old
Norse deigja ‘female servant’, ultimately from a root meaning
‘to knead’, and related to the word for dough), which he says came to
be used for a servant of either sex.
- Irish: Anglicized form of
Gaelic Ó Deaghaidh (see O’Dea).
- Scottish: from an Anglicized form of the Gaelic personal name Daìdh, a
colloquial form of David.
- Welsh: from Dai, a pet
form of the personal name Dafydd, Welsh form of David.
- This name was brought independently from many parts of Britain to
New England by many bearers from the 17th century onward. Robert Day
was one of the founders of Hartford, CT, (coming from Cambridge, MA,
with Thomas Hooker) in 1635.
