Hemly History, Family Crest & Coats of Arms
Early Origins of the Hemly family
The surname Hemly was first found in Cornwall where "Hambly is an old name of the 17th century in the parishes of St. Breward, Egloshayle, and Bodmin; in the last two localities it is still represented."  "Hamley and Hambly are fairly common surnames in Cornwall." 
"Treblethick [in the parish of St. Mabyn, Cornwall] was the seat of the Hamleys, in which family it had been for many preceding generations. But not long afterwards it became the property of Treise, from whom it passed with other estates of this family on the death of Sir Christopher Treise." 
The prevalence for Cornish roots is undeniable, but we will include another source's understanding of the name.
"The name, is apparently from Hamly Bridge in Chiddingly (Sussex), though the surname is now associated mainly with Devon and Cornwall. "

Hemly 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 Hambley, Hambly, Hamley, Hamby and others.
