Kestler History, Family Crest & Coats of Arms
Cornwall in southwestern England provides the original birthplace of the surname Kestler. As populations grew, people began to assume an extra name to avoid confusion and to further identify themselves. Unlike most Celtic peoples, who favored patronymic names, the Cornish predominantly used local surnames. This was due to the heavy political and cultural influence of the English upon the Cornish People at the time that surnames first came into use. Local surnames were derived from where a person lived, held land, or was born. While many Cornish surnames of this sort appear to be topographic surnames, which were given to people who resided near physical features such as hills, streams, churches, or types of trees, many are actually habitation surnames derived from lost or unrecorded place names. The name Kestler history began in the county of Cornwall, in the village of Kestell.
Early Origins of the Kestler family
The surname Kestler was first found in Cornwall, where the family are known to have been resident at Kestell, in the parish of Egoshayle from the time of King John till the year 1737. 
"The manor of Kestell or Kestle in the [parish of Manccan, Cornwall], was formerly the property of a family thus named, and on which they had their seat. This family becoming extinct in the male line in 1719, the barton passed in moieties with two daughters, who married Langford and Penrose. "  Now known as Kestle and Kestle Mill, these hamlets are just south of Quintrell Downs.
"The manor of Pendavy, [in the parish of Egloshayle] which was formerly connected with the priory of Bodmin, was afterwards the property of the Kestel family, from whom it passed by marriage to that of Moyle, and by this family it was sold to the Usticks, by whom it was possessed in the days of Hals. It is now the property of Sir A. O. Molesworth. Kestel, which is so called from its having had on some of its lands, a camp, castle, or intrenchment, belonged so early as the reign of King John, to a family bearing its own name. In this family it continued until the year 1734, when it was sold by James Kestel, Esq."

Kestler Spelling Variations
Cornish surnames are characterized by a multitude of spelling variations. The frequent changes in surnames are due to the fact that the Old and Middle English languages lacked definite spelling rules. The official court languages, which were Latin and French, were also influential on the spelling of a surname. Since 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, 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, which accelerated and accentuated the alterations to the spelling of various surnames. Lastly, spelling variations often resulted from the linguistic differences between the people of Cornwall and the rest of England. The Cornish spoke a unique Brythonic Celtic language which was first recorded in written documents during the 10th century. However, they became increasingly Anglicized, and Cornish became extinct as a spoken language in 1777, although it has been revived by Cornish patriots in the modern era. The name has been spelled Kestle, Kestell, Kestel, Kestelle, Kessel, Kessal and many more.
