Adult life
Robert Holt Leigh Esq. was appointed Captain-Commandant of the Wigan Volunteer Association on 17 May 1798. Leigh trained as a barrister before being returned unopposed to Parliament for the Borough of Wigan on 8 July 1802, a seat he kept until retiring in 1820. After the 1812 election he was listed as one of George Canning’s 11 personal followers returned to the new Parliament. Canning nominated Leigh as one the men whom he wanted to offer a baronetcy. The Leigh Baronetcy, of Whitley in the County of Lancaster, was created in the Baronetage of the United Kingdom on 27 December 1814 for Robert Holt Leigh. In 1830 he was one of the initial proprietors of the Wigan Branch Railway. Leigh was a feoffees of the Manchester free school in the 1830s. By this time the school was getting richer on the proceeds of the mills which provided its funding and had a growing surplus on account. Its feoffees were heavily criticised for running the school to suit the needs of their offspring rather than as originally intended, the poor of Manchester. This led to a long running suit at the Court of Chancery, which eventually promoted the commercial side at the expense of the classical side of the school. In his later years he had a notorious affair with Sarah Yates, the wife of one of his tenant farmers. He died unmarried on 21 Jan 1843 leaving a life interest in his estates to Thomas Pemberton, who assumed the additional surname of Leigh and who was subsequently raised to the peerage in his own right as Baron Kingsdown. The reversion of his estates, after Baron Kingsdown died, together with the interest on £20,000 was left to Sarah Yates' son, Roger Leigh, who Sir Robert adopted, as long as he remained a member of the Church of England.
