United States Dillon migration to the United States +

During the middle of the 19th century, Irish families often experienced extreme poverty and racial discrimination in their own homeland under English rule. Record numbers died of disease and starvation and many others, deciding against such a fate, boarded ships bound for North America. The largest influx of Irish settlers occurred with Great Potato Famine of the late 1840s. Unfortunately, many of those Irish that arrived in Canada or the United States still experienced economic and racial discrimination. Although often maligned, these Irish people were essential to the rapid development of these countries because they provided the cheap labor required for the many canals, roads, railways, and other projects required for strong national infrastructures. Eventually the Irish went on to make contributions in the less backbreaking and more intellectual arenas of commerce, education, and the arts.

The Dillon 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: Dum spiro spero
Motto Translation: While I have breath I hope.
