Early Origins of the Heyl family
The surname Heyl was first found in Brittany, where Hillion, near Saint-Brieux, was the birthplace of Herve d'Helion, a companion of William the Conqueror who was awarded a barony and lands in Devon. It is there that the family established its family seat at Ashton and Credy-Helion.
Some of the family were found in the parish of St. Ewe, Cornwall. "The manor of Heligan, was at an early period the property of the Heligans, from whom it passed by female heirs to the Tregarthians, and Whitleghs, and from the latter by co-heiresses to the families of Grenville and Hals." 
Shropshire, on the border of Wales, was of particular significance to the family. For it was here that in the Hundredorum Rolls of 1273, Philip filius Heilin, Robert filius Heilin and B'ucha uxor Heilini were recorded as holding lands at that time.

Heyl 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 Heylin, Heylen, Haylin, Hayling, Heylins, Heylens and many more.
