Petersom History, Family Crest & Coats of Arms
The background history of the name Petersom starts in ancient Scotland among the Pictish people. The name Petersom is derived from the personal name Peter. Petersom is a patronymic surname, which belongs to the category of hereditary surnames. This particular surname was taken from the popular religious given name, Peter a shortened form of St. Peter. Other patronymic names were derived from the given name of an ancestor of the bearer, while still others came from the names of secular heroes.
Early Origins of the Petersom family
The surname Petersom was first found in Aberdeenshire (Gaelic: Siorrachd Obar Dheathain), a historic county, and present day Council Area of Aberdeen, located in the Grampian region of northeastern Scotland. One of the first records of the family was found here: "Nigellus filius Petri, one of the burgenses rure manentes, Aberdeen, 1317."  The native home of the Clan Pheadirean (Patersons) was on the north side of Lochfyne where they were formerly numerous. The name is closely related to Paterson and the two spellings and many more have been used interchangeably over the years. By example, Donald Patyrson was admitted burgess of Aberdeen in 1494 and William Patrison and John Patonson, 'gentillmen,' were witnesses in Aberdeen in 1446.

Migration of the Petersom family
The freedom of the North American colonies was enticing, and many Scots left to make the great crossing. It was a long and hard journey, but its reward was a place where there was more land than people and tolerance was far easier to come by. Many of these people came together to fight for a new nation in the American War of Independence, while others remained loyal to the old order as United Empire Loyalists. The ancestors of Scots in North America have recovered much of this heritage in the 20th century through Clan societies and other such organizations. A search of immigration and passenger lists revealed many important and early immigrants to North America bearing the name of Petersom: Cornelius Peterson who settled in Maryland in 1674; Evor Peterson settled in Virginia in 1653; Henry Peterson settled in Virginia in 1622; Neale Peterson settled in Virginia in 1653.
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: Nihil sine Deo
Motto Translation: Nothing without God.
