United States Deely migration to the United States +

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 Deely:

The Deely 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
