Biographical history

The name of Milnes-Coates originated with the marriage, in 1906, of Captain Edward Clive Coates (1879-1971) of Helperby Hall, Yorkshire, and Lady Celia Hermione Crewe-Milnes (1884-1985), daughter of Sir Robert Crewe-Milnes, Marquess of Crewe, and granddaughter of Richard Monckton Milnes, 1st Baron Houghton, and his wife Annabella Hungerford Crewe. Edward was the son of Edward Feetham Coates, who had been created 1st Baronet Coates of Helperby Hall in 1911. The 1st Baronet was a member of Coates, Son & Company, stockbrokers, and Conservative Member of Parliament for Lewisham from 1903 to 1918.

In 1921 Edward succeeded his father as 2nd Baronet. Sir Edward had achieved the rank of Captain in the 15th Hussars during the First World War and had also been Military Secretary to the Lord Lieutenant of Ireland. As his father in law, the Marquess of Crewe, had no surviving male heirs, in 1946 Sir Edward took the additional name of Milnes, becoming Sir Edward Milnes-Coates. Sir Edward and Lady Celia had four children together: Robert Edward James Clive in 1907; Bridget Sibyl in 1910; Elizabeth Hermione in 1914; and Anthony Richard in 1920.

Sir Edward died in 1971 and was succeeded by Robert as 3rd Baronet. Sir Robert had served in the Coldstream Guards from 1927, serving as aide-de-camp to the Commander in Chief in India between 1930 and 1933 and then with the Transjordan Frontier Force from 1937 to 1940. He married Lady Ethel Patricia Hare, daughter of the 4th Earl of Listowel, in 1945 and the couple had two children, Mary Freda in 1947 and Anthony Robert in 1948.

Sir Robert died in 1982 and was succeeded by Anthony Robert as 4th Baronet. Since 1990 Sir Anthony has been Professor of Microbiology at St George’s Hospital Medical School in London.
