Nathaniel CRISP, the Elder:
The Burgess* Roll for Nottingham records Nathaniel, framework knitter, as enrolled in 1717. His qualification was servitude by serving an apprenticeship to a Nottingham Burgess, enrolment usual taking place upon completion around the age of 21. The Roll indicates that he was allotted a Burgess Part. He was apprenticed to George EATON of Nottingham in 1710, as s/o John of Nottingham, gentleman, deceased, noted as a framework knitter 'of London'**. The indenture was subject to a tax of £6. He does not appear in the Index of Apprentices kept by Notts Archives Office.

[* a Burgess is a Freeman of the borough.]
[** this suggest Nathaniel's baptism may be found somewhere in London]

Nathaniel "The Bishop" CRISP:
[Presumed to be the man who married Fanny HORSELEY in 1789]
From "Notes About Notts. A Collection of Singular Sayings, Curious Customs, Eccentric Epitaphs and Interesting Items, Historical & Antiquarian" by Cornelius BROWN, Nottingham, 1874. p.63:

"BISHOP CRISP: This individual was one Nathaniel CRISP, a butcher, who carried on business at the corner of Lister-gate and Broad-marsh. He was the principal baptiser during the famous duckings at Nottingham in 1794, the Leen and the canal served as the Jordan, in which the baptism by immersion took place. The sprinkling process was performed chiefly at the Exchange pump, whilst the spectators sung - "We'll pump upon them till they sing, Upon their knees, God save the King". "The Bishop" was convicted at the Spring Assizes of the following year for his riotous conduct during the ducking season, fined a nominal sum, and imprisoned for six months. He died in May, 1819."
