O'Halloran landed in England in May 1834. In February 1835 he received his knighthood at the hands of
King William IV, who observed that the distinction was well earned by his long meritorious and gallant services, and by his consecration of his eight sons to the service of his country. O'Halloran became a major-general on 10 Jan. 1837. He was made
KCB in 1837, and
GCB in 1841. He became a member of the
Royal Asiatic Society of London in 1836, was chosen an honorary member of the
Royal Irish Academy in 1838, and received the freedom of his native city of
Limerick on 25 February the same year. He died at his residence in Connaught Terrace,
Hyde Park, London, on 3 November 1843, from the effects of a street accident, causing fracture of the neck of the thigh-bone. He was buried in the catacombs at
Kensal Green cemetery, immediately beneath the chapel. A memorial tablet was placed in the wall of the south cloister. O'Halloran married, in 1790, Frances, daughter of
Colonel Nicholas Bayly, M.P., of Redhill, Surrey, late of the 1st foot-guards, and brother of the first
Earl of Uxbridge, by whom he had a large family. His sons included
