To make matters worse, medieval scribes spelled words according to sound, so names frequently appeared differently in the various documents in which they were recorded. The name was spelled Dampier, Damper, Demper, Dempier, Dammper, Dammpier, Dampere, Dampar, Dampir, Dampare, Dampire, Dammpare and many more.

United States Demper migration to the United States +

Because of this political and religious unrest within English society, many people decided to immigrate to the colonies. Families left for Ireland, North America, and Australia in enormous numbers, traveling at high cost in extremely inhospitable conditions. The New World in particular was a desirable destination, but the long voyage caused many to arrive sick and starving. Those who made it, though, were welcomed by opportunities far greater than they had known at home in England. Many of these families went on to make important contributions to the emerging nations of Canada and the United States. Analysis of immigration records indicates that some of the first North American immigrants bore the name Demper or a variant listed above:

The Demper 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: Dominus petra mea
Motto Translation: The Lord is my rock.
