When Milton Perry Eddy was born about 1816, in Litchfield, Connecticut, United States, his father, Rufus Eddy, was 39 and his mother, Clarissa Raymond, was 42. He married Susan Nelson in 1841. They were the parents of at least 1 son.
Cornish: from the personal name Edy (pronounced ‘eedy’), a variant of Udy , from the Middle English personal name Ude, Udy, 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), though in the 16th century it was sometimes unrounded to /i:/, spelled -e(e)-. It was later altered to Eddy.
English: variant of Eady .
English: perhaps from a shortened form of the Middle English personal name Edwy (Old English Ēadwīg, from ēad ‘prosperity, fortune’ + wīg ‘war’), which has not survived in that form as a surname.
