John the elder brother, a bachelor, had died without issue and before him and the estates of Crawfordsburn and Rademon passed to Arthur Johnston and his descendants.

Arthur Johnston SHARMAN-CRAWFORD (J.P. & D.L. Co Down) of Crawfordsburn and Rademon, Co Down and of Stalleen Co. Meath, become a director of The Belfast Banking Company on 8th July 1861 and eventually retired as director in 1888, when he became High Sheriff. His career ran alongside that of his fellow director, E.H. Clarke who also graduated from Trinity College, Dublin and both were called to the Bar in 1834 and worked as brother barristers on the same North East Circuit. (Arthur Johnston got his B.A. in 1831 and his M.A. in 1836 and was called to the Bar at Kings Inn, Dublin in 1834). An attempt to resign from his Directorship of the Belfast Bank in 1884 was put off at the request of the Board of Superintendence, as they could find no apparent successor for him. He agreed to an time sharing arrangement on a lower salary, for the time being. His retirement from the Directorship in 1888 was succeeded by his membership of the Bank's Board of Superintendence until his death in 1891.

Arthur Johnston's wife was Louisa Alicia, the daughter of William CRAWFORD of Cork by his second wife Mary UNIACKE, (daughter of James UNIACKE of Lakelands, Castletown, Co Cork). She was born at Lakelands and married Arthur Johnston CRAWFORD at Kilmore, Co Down on 31 March 1846 (He was her first cousin once removed - Arthur's Grandfather, John CRAWFORD and her father, William CRAWFORD were brothers)

She and Arthur Johnston had four sons and three daughters, the eldest and youngest of whom, William Henry and Arthur Frederick became involved with their maternal grandfather, William's Cork business, the Beamish and Crawford Brewery Only two of his sons, Robert Gordon and Arthur Frederick survived him.

A portrait was hung in Crawfordsburn, but its present whereabouts are unknown.

He died at Crawfordsburn in 1891

The Belfast News Letter had the following to say about him in an obituary:

The deceased was a member of a family long and intimately connected with the County of Down. The name of Sharman-Crawford is known and respected in every agricultural household, alike for the genial upright character of the family and for the interest they have ever manifested in matters affecting the welfare of the farmer.

The deceased who was of a peculiarly unobtrusive character, was no less sincere in his desire than his predecessors for land reform. He quietly but ably advocated the cause, and everything that tended to the improvement of the tiller of the soil found in him a zealous supporter.

In his time no work of a Liberal character in either Down or Belfast was promoted without his assistance. Among his party in the City, his counsels were eagerly sought after. In their choice of candidates for parliamentary or other representation, his opinion carried with it very considerable weight. The project for the erection of the Ulster Reform Club had his undivided support, and subsequently the members honoured him by electing him to the presidency.

The deceased, while a Liberal, was always opposed to the separation programme. On this question he was obliged to withdraw his support from Mr Gladstone, whom he had been pleased to follow for so many years, and to throw in his lot with the Unionist Party. Much as he respected his old leader, he failed to recognise the wisdom or justice of his proposals, and to the end of his very active life, never ceased to offer a strenuous opposition.

The deceased was called to the Bar and for some time practised on the North East circuit. Subsequently he joined the Board of Directors of the Belfast Bank, which position he held for upwards of twenty years. During this time his upright business habits, his energy and perseverance did much to promote the success of this institution.

Arthur Johnston SHARMAN-CRAWFORD was buried in the family vault at Kilmore on 8th September 1891.

His will and codicil were proved at Belfast 16th October 1891 by Robert Gordon Sharman-Crawford his third son, heir and exor. (His first son William Henry having just pre-deceased him at the age of 42 in December 1889 and his second son having died at age 12 in 1851.)
