Migration of the Cogdill family
Many English families tired of political and religious strife left Britain for the new colonies in North America. Although the trip itself offered no relief - conditions on the ships were extremely cramped, and many travelers arrived diseased, starving, and destitute - these immigrants believed the opportunities that awaited them were worth the risks. Once in the colonies, many of the families did indeed prosper and, in turn, made significant contributions to the culture and economies of the growing colonies. An inquiry into the early roots of North American families has revealed a number of immigrants bearing the name Cogdill or a variant listed above: Mary Coghill, who settled in Virginia in 1684; George Coggshill, who settled in Philadelphia, Pennsylvania in 1822; and D.J. Coghill, who arrived in San Francisco, California in 1851..
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: Non dormit qui custodit
Motto Translation: No sleep for those on guard.
