The spelling and overall form of Irish names often vary considerably. The original Gaelic form of the name Dayly is Ó Dalaigh, from the word "dalach," which comes from "dail," which means "assembly." 1

Early Origins of the Dayly family

The surname Dayly was first found in the barony of Magheradernon, in County Westmeath and traditionally claim descent from Eanna Ceannselach (Ian Kinsella), King of Leinster. They became Chiefs of Muintir Bhaire in the south west of Cork, and later in the north west of the same county, largely in O'Keefe's country. A distinct sept was found in Desmond as early as 1165.

"Cuconnachta-na-Scoil O'Daly (or "Cuconnachta of the Schools") was the first of this family that assumed the surname." 2

Dayly Spelling Variations

During the Middle Ages, a standardized literary language known by the general population of Ireland was a thing of fiction.

Research into the name Dayly revealed many variations, including Daly, Daley, Daylie, Dayley, Dalley, Dailey, Daily, Dailley, Dally, O'Daily, O'Daley and many more.

Canada Dayly migration to Canada +

Thousands of Irish left in their homeland in the 18th and 19th centuries to escape the religious and political discrimination they experienced primarily at the hands of the English, and in the search of a plot of land to call their own. These immigrants arrived at the eastern shores of North America, early on settling and breaking the land, and, later, building the bridges, canals, and railroads essential to the emerging nations of United States and Canada. Many others would toil for low wages in the dangerous factories of the day. Although there had been a steady migration of Irish to North America over these years, the greatest influx of Irish immigrants came to North America during the Great Potato Famine of the late 1840s. Early North American immigration records have revealed a number of people bearing the Irish name Dayly or a variant listed above:

The Dayly Motto +

The motto was originally a war cry or slogan. Mottoes first began to be shown with arms in the 14th and 15th centuries, but were not in general use until the 17th century. Thus the oldest coats of arms generally do not include a motto. Mottoes seldom form part of the grant of arms: Under most heraldic authorities, a motto is an optional component of the coat of arms, and can be added to or changed at will; many families have chosen not to display a motto.

Motto: Deo fidelis et Regi
Motto Translation: Loyal to God and king
