Rupert Baring, 4th Baron Revelstoke

Rupert Alexander Baring, 4th Baron Revelstoke (8 February 1911 – 18 July 1994) was a British landowner and peer.

Early life Baring was born in London on 8 February 1911. He was the only son of Cecil Baring, 3rd Baron Revelstoke and Maude Louise (née Lorillard) Tailer. His parents met in New York, where his father was working for Kidder, Peabody & Co., which led his mother to divorce her first husband, Thomas Suffern Tailer (a son of Edward Neufville Tailer), who was one of his father's business partners. From his parents marriage, he had two sisters, Hon. Daphne Baring (wife of Arthur Joseph Lawrence Pollen, eldest son of Arthur Pollen and grandson of Sir Joseph Lawrence)

His paternal grandparents were the former Louisa Emily Charlotte Bulteel (a daughter of John Crocker Bulteel, MP) and Edward Baring, 1st Baron Revelstoke, the senior partner in the family banking firm of Baring Brothers and Co. Among his large extended paternal family were uncles John Baring, 2nd Baron Revelstoke, the prominent banker, Brigadier-General Everard Baring and novelist and Russophile Maurice Baring. His aunt, Margaret, was the wife of Charles Spencer, 6th Earl Spencer.

Baring attended Eton and Trinity College, Cambridge. When he broke off the "engagement", she sued him for breach of promise of marriage. Revelstoke "refused to settle and endured having his love letters read out in court and published in the newspapers." Joyce's suit, which generated significant press interest, was unsuccessful, and led to the law being changed whereby a woman could "not be able to claim damages for not obtaining the position she hoped for as the wife of a rich man." Revelstoke was the last man to be sued in this way.

John Baring, 5th Baron Revelstoke (1934–2003), who died without issue.

In popular culture The lawsuit against Revelstoke by Angela Joyce was depicted in the drama series The Duchess of Duke Street in 1977, where the character based on Revelstoke, Lord Haslemere, was played by the young Christopher Cazenove.
