Dagg Family History

English: perhaps from Old French dague ‘dagger’ or from Middle English dagge (a borrowing of dague) though the latter is recorded only with the senses ‘ornamental points or incisions on the edges of a garment’ and ‘shred tag or strip (as of cloth or leather)’. The name may have been given to one who wore dagged jagged garments or (if the name is of Anglo-Norman origin) to one who wore a dagger. Compare Daggett.

Middle English Dagger is a later development of the same word. The surname was taken to southern Ireland in the 17th century. English: from either an Old French personal name Dague (ancient Germanic Dago ‘day’ or if ultimately of Celtic origin meaning ‘good’) or an Anglo-Norman personal name Dag(g) (a pet form of names in Dag- such as Dagobert). Compare Tagg.

German: from a personal name based on Old High German tac ‘day’. See
