Sir Thomas Pengelly (16 May 1675[1] – 14 April 1730) was a British lawyer, judge, novelist and later the Member of Parliament for Cockermouth, serving from 1722 to 1727, and Lord Justice of Appeal in 1726.
in 1696, Cromwell continued to lodge with Mrs Pengelly, moving with her to her property in Cheshunt in Hertfordshire in 1700,[3] and remaining there until his own death in 1712.
As Prime Serjeant he was involved in the trial of the Jacobite plotter Christopher Layer for high treason in early 1722.
During his five years in Parliament he was involved in various legal matters, including pursuing the directors of the South Sea Company.
In 1725 he was involved in the impeachment of the Lord Chancellor, Lord Macclesfield, who had sold positions to several Masters of Chancery and who, in an attempt to regain the high cost of the bribes required to buy their offices, had subsequently invested and lost their clients' money in the South Sea Bubble crash.
