Early life
Robert Vernon Atherton Gwillym was born on 28 August 1741, the second son of Robert Gwillym of Langstone Court, Herefordshire,[1] and his wife, Elizabeth Atherton (1721–1763). Through his mother, he was connected to one of Lancashire's most prominent landed families, whose wealth and influence had been established through landownership, commerce, and political service.
His maternal grandparents were Richard Atherton (1700–1726) of Atherton Hall and Elizabeth Farrington.[2] The Atherton’s were among the leading families of south Lancashire and had long been associated with Atherton Hall, the family's ancestral seat. Through this lineage, Gwillym was a direct descendant of the Atherton family and ultimately became heir to a substantial estate that strengthened his position within the British landed gentry.
Raised between the social worlds of the Herefordshire gentry and the Lancashire landowning elite, Gwillym benefited from family connections that provided opportunities for advancement in public life. These relationships, together with the inheritance he later acquired through the Atherton line, contributed to his emergence as a figure of local and national importance during the eighteenth century.
Following the extinction of the senior male line of the Atherton family, Gwillym inherited the Atherton estates and, in 1779, assumed the surname Atherton in accordance with the terms of the inheritance. Thereafter he was known as Robert Vernon Atherton, a name that reflected his succession to one of Lancashire's most distinguished landed families.
Career
He succeeded his brother William in 1771, and inherited Atherton Hall, Leigh. That same year he is listed as a subscriber to a journal on travels to America and of agriculture and plantations.
At the 1774 general election, Gwillym was returned unopposed as Member of Parliament for Newton on the interest of his father-in-law. His attendance in Parliament was very infrequent as he suffered from poor health. His only recorded vote was for Wilkes's Middlesex resolution, and he is not recorded as having spoken. He did not stand at the 1780 general election.
