Grennant History, Family Crest & Coats of Arms
The ancient Norman culture that was established in England after the Conquest of 1066 produced the name of Grennant. It was given to a person who had a moustache. The name was originally derived from Old English words gernon or grenon, which meant moustache.
Early Origins of the Grennant family
The surname Grennant was first found in Montfiquet, in the district of Bayeux. Robert de Guernon accompanied the William the Conqueror at Hastings in 1066 A.D. Robert held estates in Herefordshire, Suffolk, and a great barony in Essex. Another early notable of the family was Ranulf II (also known as Ranulf de Gernon) (1099-1153), a Norman-born, potentate who inherited the honour of the palatine county of Chester. He claimed descent from the Counts of Bessin in Normandy.
Thoydon-Garnon in Essex was and ancient homestead of the family. "The parish takes the adjunct to its name from the family of Gernon, who were anciently its proprietors."  Great and Little Birch in Essex was an ancient family seat. "Birch Castle was fortified against Henry III. by Sir Ralph Gernon, then lord of the manor: there are still some remains."

Grennant Spelling Variations
Multitudes of spelling variations are a hallmark of Anglo Norman names. Most of these names evolved in the 11th and 12th century, in the time after the Normans introduced their own Norman French language into a country where Old and Middle English had no spelling rules and the languages of the court were French and Latin. 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 Garnon, Garnons, Gernan, Gernon, Gernen, Garnham and many more.

Migration of the Grennant family to Ireland
Some of the Grennant family moved to Ireland, but this topic is not covered in this excerpt.
Migration of the Grennant family
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 Grennant 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 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.
