Greville was educated at Rugby School and entered the Army, at first in the 3rd (Militia) Battalion Argyll and Sutherland Highlanders and then the 1st Life Guards.[2] Greville resigned his commission as a captain in 1896 when he was elected as a Member of Parliament.[2][5]
On 25 April 1891, he married Margaret Helen Anderson (1863–1942).[4] Margaret was the illegitimate daughter of William McEwan, a multimillionaire brewer (later elected as an MP for Edinburgh Central)[8][9] and his mistress, Helen Anderson, a cook who married McEwan after her first husband's death in 1885.[10] After their marriage, they lived at Polesden Lacey, in Great Bookham, Surrey, a gift from his wife's father.[4]
On 5 April 1908, when Greville was 43, he died from pneumonia following an operation, predeceasing his own father and never acceding to the peerage.[2] As Ronald had no children, after his father's death the following December 1909,[11] his younger brother Charles became the 3rd Baron Greville.[12]
