The Honourable Gerald Valerian Wellesley (1770–1848) was a British clergyman of the Church of Ireland.
When he was born his family were part of the Anglo-Irish Protestant Ascendancy based in Trim, County Meath.
[1] He rose to be Prebendary of Durham, but future promotion was halted by his complex relationship with his wife Lady Emily Cadogan whom Wellesley had married while he was a rector in Chelsea.
In 1826 he was a source of conflict between his brother Wellington and his political ally the Prime Minister Lord Liverpool.
Wellington pushed for his brother to be granted a vacant Irish bishopric, and was supported by Richard who was now the Viceroy of Ireland, but Liverpool objected as he was living with a woman who wasn't his wife.
