Mayne inherited estates in Ireland through his marriage in 1758 to the Hon. Frances Allen, daughter of Joshua Allen, 2nd Viscount Allen, and heir of her brother John Allen, 3rd Viscount. Through this connection Mayne served as an Irish MP for Carysfort in 1761-76, standing as a member of the Irish Privy Council in 1766, and then as a British MP for Canterbury in 1774-80, and Gatton in 1780-90. Throughout his career in British politics Mayne was an advocate of leniency towards the Irish, and of lifting restrictions on Irish trade. He did, however, object to American independence, being especially concerned for the welfare of the loyalist community. He was created Baronet of Marston Mortaine, Bedfordshire, in 1763, and Baron Newhaven of Carrick Mayne, County Dublin, in 1776. The marriage between William Mayne and Frances Allen produced one son, but he died in infancy, and Mayne's titles became extinct on his death in 1794.
Sir William and his brother Robert were both subscribers to Adam's Ruins of the Palace of the Emperor Diocletian at Spalatro in Dalmatia in 1764. It was presumably by these means that Adam was known to him, and in 1771, Sir William commissioned Adam to make designs for the interior decoration of his house on Wimpole Street. It is not known how extensive this commission was, but there are surviving drawings for a ceiling, a chimneypiece and overmantel, and mirror frames for an unknown room or rooms. It is possible that these designs were executed, but this is not known. The house was destroyed during the Second World War, and is now one of the offices of the General Dental Council; it is currently under consideration for planning permission for an extension to its twentieth-century building, along with extensive internal rearrangement, proposed to be undertaken during 2014.

Sir John Soane's collection includes some 30,000 architectural, design and topographical drawings which is a very important resource for scholars worldwide. His was the first architect’s collection to attempt to preserve the best in design for the architectural profession in the future, and it did so by assembling as exemplars surviving drawings by great Renaissance masters and by the leading architects in Britain in the 17th and 18th centuries and his near contemporaries such as Sir William Chambers, Robert Adam and George Dance the Younger. These drawings sit side by side with 9,000 drawings in Soane’s own hand or those of the pupils in his office, covering his early work as a student, his time in Italy and the drawings produced in the course of his architectural practice from 1780 until the 1830s.
Browse (via the vertical menu to the left) and search results for Drawings include a mixture of Concise catalogue records – drawn from an outline list of the collection – and fuller records where drawings have been catalogued in more detail (an ongoing process).
