Chennings History, Family Crest & Coats of Arms
The ancient surname Chennings came from The name Chennings is derived from the personal name John, or perhaps more accurately from several diminutions of the name John, such as Jan, Jon, or Jen. 
Patronymic surnames belong to the larger category of surnames, known as hereditary surnames, and they arose out of the vernacular and religious given name traditions. In the religious naming tradition, which was developed later than the vernacular tradition, surnames were bestowed in honor of religious figures or church officials. In Europe, the Christian Church was one of the most powerful influences on the formation of given names. Personal names derived from the names of saints, apostles, biblical figures, and missionaries are widespread in most European countries. In the Middle Ages, they became increasingly popular because people believed that the souls of the deceased continued to be involved in this world. They named their children after saints in the hope that the child would be blessed or protected by the saint. John, of course, is derived from John the Baptist, who was born in order to announce Christ's coming.

Chennings Spelling Variations
Since the Old and Middle English languages lacked definite spelling rules, Breton surnames have many spelling variations. Latin and French, which were the official court languages, were also influential on the spelling of surnames. The spelling of surnames was rarely consistent in medieval times, and scribes and church officials recorded names as they sounded rather than adhering to any specific spelling rules. Therefore, it was common to find the same individual referred to with different spellings of their surname in the ancient chronicles. Moreover, a large number of foreign names were brought into England after the Norman Conquest, which accelerated and accentuated the alterations to the spelling of various surnames. The name has been spelled Jennings, Jenings, Jennins, Jennyns, Jennens, Jennynge, Jennynges, Jenyns and many more.
