[1] He was educated at Westminster School from 1745 to 1751 and matriculated at Christ Church, Oxford in 1751. [2] On the death of his father on 24 March 1758 he succeeded to the baronetcy.

Political career

Mostyn was returned unopposed as Member of Parliament for Flintshire at a by-election on 26 April 1758 replacing his late father. His family had the dominant electoral interest in Flintshire and he was returned unopposed at general elections in 1761, 1768, 1774, 1780, 1784, 1790 and 1796. [4] Mostyn was a Whig whose voting record became a concern to his constituents, and in 1784 his brother-in-law, Thomas Pennant of Downing, threatened to create an opposition although nothing came of it. [4]

Mostyn served as Lord Lieutenant of Flintshire from 1761 to his death and Custos Rotulorum of Flintshire from 1772 to his death. He was a Lieutenant-Colonel in the Flintshire Militia. [4]

Later life and legacy

He was succeeded in the baronetcy and Parliamentary seat by Thomas, who died unmarried, causing the baronetcy to become extinct. Of his daughters, Charlotte married Sir Thomas Swymmer Mostyn-Champneys, 2nd Bt, Elizabeth married Sir Edward Pryce Lloyd, 2nd Bt and Anna-Maria married Sir Robert Williames Vaughan, 2nd Bt, while Catherine, Essex and Maria Bridget were unmarried.
