Eldest son of Montague Ainslie, sometime of Bengal,[1] and Sophia Mary, daughter of George Poyntz Ricketts,[2] he was born at Humeerpore in British India.
[1] Ainslie had a successful career as a barrister; from the 1860s until 1871, he was counsel to the Speaker of the House of Commons, and was examiner of election recognizances.
[6] A poor batsman of unknown-handedness, Ainslie scored 98 runs in his ten first-class matches, averaging just 5.44.
[7] As a bowler it is known he took 4 wickets, however due to incomplete records, it is only known that he took a maximum of 3 in one innings.
[7] Ainslie inherited his father's property, Hawkshead, at Grizedale, Ambleside, on the east side of Windermere, Westmorland (the estate, per some accounts, reckoned to be part of Lancashire),[4][8] where he died on 22 March 1896.
