Dalay History, Family Crest & Coats of Arms
The spelling and overall form of Irish names often vary considerably. The original Gaelic form of the name Dalay is O Dalaigh, from the word "dalach," which comes from "dail," which means "assembly."
Early Origins of the Dalay family
The surname Dalay 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."

Early Notables of the Dalay family (pre 1700)
Notable amongst the family name at this time was Daniel O'Daly (1595-1662), Irish diplomat and historian.

Migration of the Dalay family
The 18th century saw the slow yet steady emigration of Irish families to British North America and the United States. Those early Irish settlers that left their homeland were typically moderately well off: they were enticed by the promise of a sizable plot of land. However, by the 1840s, this pattern of immigration was gone: immigrants to North America were seeking refuge from the starvation and disease that the Great Potato Famine of that decade brought. The great numbers of Irish that arrived to the United States and the soon to be Canada were instrumental in their quick development as powerful industrial nations. An examination of early immigration and passenger lists uncovered many early immigrants bearing the name Dalay: the Widow Daley who settled in Canada in 1846.
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
