William Mayne, 1st Baron Newhaven
William Mayne, 1st Baron Newhaven PC (1722 – 28 May 1794), known as Sir William Mayne, Bt, between 1763 and 1776, was a British politician.
Mayne was the eldest son of the second marriage of William Mayne, of Powis Logie, Clackmannanshire.[1] He was returned to the Irish House of Commons in 1761 for Carysfort, a seat he held until 1776.[2] He was created a Baronet, of Marston Mortaine in the County of Bedford, in the Baronetage of Great Britain in 1763[3] and sworn of the Irish Privy Council in 1766.[4] In 1774 he was elected to the British House of Commons for Canterbury.[5] Two years later he was elevated to the Peerage of Ireland as Baron Newhaven, of Carrick Mayne in the County of Dublin.[6] He continued to represent Canterbury until 1780[5] and then sat for Gatton until 1790.[7]
Lord Newhaven married the Honourable Frances Allen, daughter of Joshua Allen, 2nd Viscount Allen, and co-heir of her brother John Allen, 3rd Viscount Allen, through which marriage he gained a considerable estate. They had one son who died in infancy. Lord Newhaven died in May 1794 when the baronetcy and barony became extinct.[1]
