"[4] Francis I (of Lees Hall, Derby and Putney) was one of the Six Clerks of Chancery (and married Mary Burton).
[6] The clerkship of the Worshipful Company of Skinners stayed in the extended Gregg family for over a century (see below).
[1] He became a lawyer in practice at Skinners's Hall, Dowgate Hill, London, in the substantial legal firm Gregg & Potts.
[1] Their children included: Henry Gregg (c.1759–1826, aged 66 at death)[23][24][25] was a barrister of Lincoln's Inn, distinguished mainly as a London social figure.
[12] That year, he is styled "Student" of Christ Church (equivalent to Fellow in other colleges) in a book subscription list.
[28] Travelling the northern circuit as a barrister, Gregg took James Boswell to visit Naworth Castle, on 24 July 1788, where he had "plenary power" as an agent through his father's position with the Howards.
He dined and drank in 1790–1 with James Boswell (who admired of one of his young daughters), in company with Thomas Bever and Caleb Whitefoord.
[35] Another poem written by Parsons commemorated a dinner invitation from Gregg, with Robert Nares and William Boscawen.
