Migration of the Dilleant family to the New World and Oceana
Ireland's Great Potato Famine
left the country's inhabitants in extreme poverty and starvation. Many families left their homeland for North America for the promise of work, freedom and land ownership. Although the Irish were not free of economic and racial discrimination in North America, they did contribute greatly to the rapid development of bridges, canals, roads, and railways. Eventually, they would be accepted in other areas such as commerce, education, and the arts. An examination of immigration and passenger lists revealed many bearing the name Dilleant: William Dillon who settled in St. John's, Newfoundland in 1796; John Dillon settled in St. John's in 1814; Moses Dillon settled in Harbour Grace in 1814.
The Dilleant 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.
