Turner, Thomas (1743N/A
According to Clements, this is the stamp of Thomas Turner of Gloucester, whose library was sold by Puttick and Simpson's 20 June 1860. Thomas Turner, son of John Turner of King's Stanley in Gloucestershire, matriculated at Pembroke College, Oxford, aged twenty, on 18 November 1763. He took his B.A. in 1775, and was admitted to the degree of B.A. of King's College Cambridge and took his M.A. there in 1795. These are the arms, crest and motto of the Turner family, baronets of Ambrosden in Oxfordshire, though the ancestor of the present baronet took the name and arms of Dryden. It would seem that T. Turner was a member of that family.
Another possibility is Thomas Turner (d. 1863), the son of John Turner and Hester Warren. He was a banker, and lived at Hill View Manor in Gloucester.
