Etymology of Diack

What does the name Diack mean?

The Norman Conquest of England in 1066 brought many new words to England from which surnames were formed. Diack was one of these new Norman names. It was specifically tailored to its first bearer, who was a person who had a duck-like gait or bore some other resemblance to a duck. The surname Diack 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 Diack family

The surname Diack 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.) 1

The Rotuli Curiae Regis listed Ralph Dux of Buckinghamshire, 1198. 2

In Cheshire, two early listing were found: Robert Ducke was listed in the Assize Rolls of 1260 and later; Hugo Doke was listed in the Hundredorum Rolls of 1279. 3 In the Yorkshire Poll Tax Rolls of 1379, we found Adam Doke listed as holding lands there at that time. 4

In Devon, we found the variant Duckham. 5 "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." 6

Diack Spelling Variations

A multitude of spelling variations characterize Norman surnames. Many variations occurred because Old and Middle English lacked any definite spelling rules. The introduction of Norman French to England also had a pronounced effect, as did the court languages of Latin and French. Therefore, one person was often referred to by several different spellings in a single lifetime. The various spellings include Duck, Duche, Ducke, Dack, Diack and others.
