United States McDonnaugh migration to the United States +

Suffering from poverty and racial discrimination, thousands of Irish families left the island in the 19th century for North America aboard cramped passenger ships. The early migrants became settlers of small tracts of land, and those that came later were often employed in the new cities or transitional work camps. The largest influx of Irish settlers occurred with Great Potato Famine during the late 1840s. Although the immigrants from this period were often maligned when they arrived in the United States, they provided the cheap labor that was necessary for the development of that country as an industrial power. Early immigration and passenger lists have revealed many immigrants bearing the name McDonnaugh:

The McDonnaugh 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: Virtutis gloria merces
Motto Translation: Glory is the reward of valour.
