Daymon Family History

English (Cornwall): from a variant of the Middle English personal name Dayman which has a number of explanations. It may be from an Old English Dægmann perhaps a pet form of names in Dæg- ‘day’. Alternatively the name may be a pet form of the Middle English personal name Day to which the hypocoristic suffix -man has been added.

Day is sometimes a short form of David but is also a 14th-century variant of Daw a rhyming pet form of Ralph. The name may also be an occupational name for a dairyman from Middle English daie ‘man in charge of dairy cattle’ + man ‘servant worker’ similar in usage to Old English Flotmann ‘sailor’;

or an occupational name for a ‘servant of a man named Day’. Daymon is also a variant of Diamond. This form of the surname is now rare in Britain.
