The Anglo-Saxon name Jem comes from the baptismal name John or Joan. The surname Jem referred to the son of John or Joan which belongs to the category of patronymic or metronymic surnames. In Old English, patronyms and matronyms were formed by adding a variety of suffixes to personal names, which changed over time and from place to place. For example, after the Norman Conquest, sunu and sune, which meant son, were the most common patronymic suffixes. In the 12th and 13th centuries, the most common patronymic names included the word filius, which meant son. By the 14th century, the suffix son had replaced these earlier versions. Surnames that were formed with filius or son were more common in the north of England and it was here that the number of individuals without surnames was greatest at this time.

Migration of the Jem family

To escape oppression and starvation at that time, many English families left for the "open frontiers" of the New World with all its perceived opportunities. In droves people migrated to the many British colonies, those in North America in particular, paying high rates for passages in cramped, unsafe ships. Although many of the settlers did not make the long passage alive, those who did see the shores of North America perceived great opportunities before them. Many of the families that came from England went on to make essential contributions to the emerging nations of Canada and the United States. Research into various historical records revealed some of first members of the Jem family emigrate to North America: John Jennet settled in Pennsylvania in 1682; Peter Jennett arrived in Maryland in 1776.
