Dax History, Family Crest & Coats of Arms
Soon after the Norman Conquest of England in 1066, the name Dax was recognized on the island as a name for a person who had a duck-like gait or bore some other resemblance to a duck. The surname Dax is derived from Old English words duk, dukke, duck, doke, and dook, which all mean duck. However, these words are often indistinguishable from the various Old English words duc, duk, duke, douc, and doke, which all came from the Old French word duc. This ultimately came from the Latin word dux, which means leader, and is a derivative of the verb ducere, which means to lead.
Early Origins of the Dax family
The surname Dax was first found in Somerset where the first record of the family was John le Duk, who was listed there 1 Edward III (during the first year of King Edward III's reign.)

In Devon, we found the variant Duckham.  "Amongst old Tiverton [,Devon] names, now scantily to be found in the county, but still surviving in this town, are Duckham This name is now established in Monmouthshire. The Duckhams were Tiverton churchwardens in 1691, 1703, and 1743."

Dax Spelling Variations
Norman surnames are characterized by a multitude of spelling variations. The frequent changes in surnames are largely due to the fact that the Old and Middle English languages lacked definite spelling rules. The introduction of Norman French to England, as well as the official court languages of Latin and French, also had pronounced influences on the spelling of surnames. Since medieval 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. The name has been spelled Duck, Duche, Ducke and others.

Overcrowding on the ships caused the majority of the immigrants to arrive diseased, famished, and destitute from the long journey across the stormy Atlantic. Despite these hardships, many of the families prospered and went on to make invaluable contributions to the development of the cultures of the United States and Canada. Early North American immigration records have revealed a number of people bearing the name Dax or a variant listed above:
