Cordiner = shoemaker!
Spot on. The detailed origin of the word is interesting.
Cordiner is from an older word, cordwainer. A cordwainer worked specifically with soft, fine, high-quality leather, known as Cordovan leather because that was where it was produced.
In Scotland a cordwainer wasn't just a common-or-garden shoemaker. His products were considered to be a cut above everyday boots or brogues.
In 1722 the cordiners of Hawick petitioned the council to be incorporated and separated from the shoe-makers ‘or those who make single-soled shoes'. In Edinburgh, the cordiners were erected into a fraternity in 1349.
However the word is documented in Scotland almost 100 years before the Armada, and there is a record of its use as a surname as early as 1422, when Thomas Cordonar was admitted a burgess of Aberdeen. A Radulph Cordwan was a tenant in Perth in about 1330 though this may just indicate that he was a native or Cordoba rather than actually using it as a surname.
