What does the name Day mean?

The Day surname has English, Welsh and Scottish roots. In Scotland and Wales it is sometimes used as a patronymic, a derivation of those who are the son or descendant of Dai (a Welsh diminutive of Dafydd) or David. More prevalently, in England Day comes from the Middle English 'Deye' (dairy-servant), and is occupational. This version of the Day surname would be given to those who made their living as dairy workers, and their descendants.

Alternative variations of the name Day

I’ve managed to trace back to the mid-1500s! I can’t believe it! Utterly engrossing and I have uncovered some quite moving and heartbreaking stories attached to various ancestors. You don’t need any qualifications to start - just time patience, and some information.
