Diffley Surname Meaning
From Where Does The Surname Originate? meaning and history
These are anglicized forms of Ó Duibhghiolla, the name of two distinct septs-of the southern Uí Fiachrach and of the Siol Anmchadha-both of Co. Galway. Diffley and Deffely are more usual in the adjoining county of Roscommon. In Co. Galway Deely too is a well known synonym; and another is Duffley. Devally is a modern variant. Devilly is pronounced with the emphasis on the first syllable — its variants Diffley etc. illustrate this-so that the I of the second syllable is almost silent, and a century or more ago, when the spelling of names was not consistent, a Devilly birth could thus be registered as Devally, and later the influence of the written word resulted in this becoming De-valley in speech.
Among the"synonyms reported by local registrars and recorded by the registrar-general in 1901 Duvalley is noted as interchangeable with Diviney in the Ballinrobe, Co. Mayo, district. This is a form of Ó Duibheannaigh, normally anglicized as Devanny, Divenney etc. (See More Irish Families pp. 87, 38). I presume the rare name Diffney is another variant of Diviney.
A variant of Devilly, q.v
