Captain Samuel Sharpe assumed the name and arms of Pocklington on his marriage in 1769 to Pleasance Pykarell, who had previously changed her name to Pocklington as a condition of inheriting the manor of Chelsworth, in Suffolk, from Robert Pocklington, her cousin. Samuel Sharpe Pocklington joined the Third Foot (later Scots) Guards of the Royal Army in 1760. He apparently resigned from this service shortly after his marriage. He commissioned a marriage portrait (see NGA 1952.9.4) from the English painter George Stubbs. The couple's son, Colonel Robert Pocklington, (later Sir) married Catherine Blagrave of Watchfield, Shrivenham.
