Cornish and English (Cornwall): of Norman origin, from the Middle English personal name Ude, Udy (Cornish Edy), Latinized as Udo and Odo. It may represent Old French Eude (ancient Germanic Eudo, of uncertain etymology), whose usual Latin form is Eudo. This agrees with later evidence that the original pronunciation of the initial vowel of Udy was /y:/ (as in French tu). Compare Eddy .
