Scribes and monks in the Middle Ages spelled names they sounded, so it is common to find several variations that refer to a single person. As the English language changed and incorporated elements of other European languages such as Norman French and Latin, even literate people regularly changed the spelling of their names.

Migration of the Grennane family

Faced with the chaos present in England at that time, many English families looked towards the open frontiers of the New World with its opportunities to escape oppression and starvation. People migrated to North America, as well as Australia and Ireland in droves, paying exorbitant rates for passages in cramped, unsafe ships. Many of the settlers did not make the long passage alive, but those who did see the shores of North America were welcomed with great opportunity. Many of the families that came from England went on to make essential contributions to the emerging nations of Canada and the United States. Some of the first immigrants to cross the Atlantic and come to North America carried the name Grennane, or a variant listed above: Roger Garnons, who sailed to America in 1658; Judith Garnon to America in 1763; William Garnons to America in 1770; and Richard Gernon to Philadelphia in 1797..



The Grennane 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: Nid cyfoeth
Motto Translation: Not wealth, but contentment.(Welsh.
