The son of Sir John Wallington, he was born in December 1854 at Oakley, Hampshire.
He was described as a cricketer by Scores and Biographies as “a good batsman with steady defence, a slow under-hand bowler and fields well, generally taking point, cover-point or short leg.”[5] Entering into the Civil Service from Oxford, Wallington later served as private secretary to Lord Carrington, the Governor of New South Wales, from 1885 to 1889, before serving as private secretary from 1889–96 to both Lord Hopetoun and Lord Brassey during their terms as Governor of Victoria.
He then served in the same capacity from 1896 to 1900 for Sir Thomas Buxton and Lord Tennyson during their terms as Governor of South Australia.
[6] Returning to the United Kingdom, he was appointed Groom of the Bedchamber to the Prince of Wales (later King George V) on 2 February 1903,[7] serving his son Prince Edward, a position within the Royal household he would hold until 1910.
[10] Wallington died a year after retiring from the Royal Household, in December 1933 at Widcombe, Somerset.
