This looks interesting in the light of the "colourman" occupation.
Freedom of the City Admission Papers
Dyers' Hall, 4th March 1829
This is to certify that William Atchison son of David Atchison of Hoxton New Town in the county of Middlesex Dyer and Citizen and Dyer of London
was this day admitted to the Freedom of the Worshipful Company of Dyers, by patrimony.
In the City of London's corresponding record, William is described as having been "born without the Liberty of the City, to wit at Old St Square, St Luke" in 1803.
His father David's admission to the Worshipful Company of Dyers is said to have been dated 1792. William's claim to be admitted into the Freedom of the City is said to be by Patrimony, in the said company of Dyers, "because he is legitimate, and was born after the admission of his Father into the said Freedom".
