I've also now got my hands on a copy of The Shining Bann by R. M. Sibbett (1928). Here's the extract about the Hill family:
The Rev. John Hill, Presbyterian minister, was the first of his name to reside in the manor of Cashel. His son, John Hill, linen merchant, founded the Hillmount Bleachworks at Cullybackey, now among the largest and best-equipped of their kind in the world.
Elizabeth, eldest daughter of John Hill, of Hillmount, married William Adams, of Portglenone, in 1789. The two youngest members of the large family by this union – a son and a daughter – went to Australia. There the former, Robert, became a successful sheep farmer, and the latter wed another colonist following the same occupation. Harry Adams the last-born son of Robert Adams, acquired considerable fame as a skilful surgeon. He died later near Wellington, New Zealand. Captain Adams, the only son of Harry Adams, was killed in the Great War. His sister, Lady Glenny Wilson, well known in the literary worlds, resides in New Zealand.
George Hill Adams, M.D., Edinburgh, was another son of William Adams. Practising for some years in Australia, he returned to London, and died at Notting Hill, unmarried. Elizabeth, the eldest daughter of the worthy couple indicated, married the Rev. W. C. Wray, of Buckna, County Antrim. One of the sons born of this union, Dr. Charles Wray, was appointed health officer of Brisbane. He died there in 1902, of Bubonic plague, caught in the discharge of his duty.
Ann Adams, the second daughter of William Adams, wed the Rev. Clarke Huston, D.D., Macosquin. William, his fourth son, espoused Sarah Adair, daughter of Henry Newton Raphael of Galgorm. Their son, George Hill Adams, was identified for some time with the York Street Flax Spinning Company, Ltd., Belfast. Eventually he went to Australia, and still resides there, at Melbourne.
Three of his sons served in the Great War - Captain George Hill Adams, M.C., Australian Artillery; Commander Bryan Fullerton Adams, R.N., D.S.O ; and Wm, Ronald Adams, Australian Field Ambulance.
The last named is now a barrister in Melboune, holding a Government appointment. His brother Bryan, by heroism, covered himself with glory. The Naval Gazette, published some time after the Zeebrudde raid stated: "Lieut.-Commander Bryan F Adams led the naval storming party in the most gallant manner. He was the first to land on the Mole. Followed by his men, he bombed the German lookout, making it useless to them, etc., etc."
Specially promoted Commander for his services, and given charge of his own ship, Bryan had conferred upon him the D.S.O. as an additional honour. He was lately appointed to the Queen Elizabeth, stationed at Malta, where Sir George Keyes, K.C.B., flies his flag.
The eldest sister of George Hill Adams wed the Rev. S. Thomson, B.A. Another became the wife of James Gardiner, a Belfast merchant. Of this marriage there were two sons, James, who succeeded his father in business, and Campbell, a successful medical practitioner. A third sister was united in matrimony to the Rev. Clarke Huston Irwin, M.A., D.D., secretary of the Religious Tract Society. A fourth sister, E. R. Adams, resides in Belfast.
William Adams, son of Thomas Adams, and grandson of William Adams and Elizabeth Hill, resided in Portglenone, and was an elder in Third Portglenone Presbyterian Church. His daughter, Annie Adams, who occupies the old mansion, maintains the high traditions of her family in the educational and musical spheres.
The Rev. Dr. Park, one-time Moderator of the General Assembly, and many others, including solicitors, barristers, doctors, and men of business, could also claim descend from the Rev. John Hill.
Other family associations may be traces through the Hills mentioned. John Hill, of Hillmount, married Anne Barry, of Carrickfergus. Anne Barry's mother was Anne Coleman, a daughter of Dr. John Coleman, of Carrickfergus. Elizabeth Coleman, sister of Mrs. Barry, wed first Dr. Dobbin, of Belfast, and secondly Henry Ellis, barrister-at-law, Innisrush. Mrs. Ellis was a grand-aunt to Elizabeth Hill, who married William Adams, Portglenone. After the death of Henry Ellis, Mrs. Ellis resided for a time in WIlliam Adams's house, where she died. Her letters, which are still preserved, show that she was quite a personality.
The youngest child of John Hill married her cousin, George Hill, of Larne. One of her daughters became the wife of a member of the McNeill family in Larne, related to the Portglenone McNeills. A son and daughter born of this union wed a Portglenone sister and brother respectively. The Larne McNeills, connected with the Hills of Hillmount, followed the legal profession. A solicitor of their name consulted by the Grand Jurors of Cashel resided in a beautiful cottage at Glenone, the side of which is now occupied by James Heenan's residence. He was half-brother to Dr. McNeill, Portglenone.
