In 1836, 2560 acres in the Upper William's River promised to Archibald Mossman by Governor Darling on 6th February, 1829 was re-advertised in favour of John Lord.

They were raided by bushrangers in December 1840. The Sydney Herald reported:

On Tuesday last, the 1st instant another posse of these freebooters made an attack on the establishment of John Lord, Esq., at Underbank (sixteen miles above Dungog), bailed up all the servants, Mrs. Lord, and Mr. Craig and after carrying away all the ammunition and fire arms they could lay their hands upon, together with tea, sugar, flour, butter etc., besides 8 or 10 in cash and a horse, they left at about half past four in the afternoon after dining comfortably and pursued their course over the mountains in the direction of the Paterson and have not since been heard of.

In March 1844 the Maitland Mercury reported the following incident that took place on this estate

'Fatal Accident. A melancholy accident occurred in this neighbourhood on Friday, the 16th February. A day or two previous Mr. John Ashworth, Mr. Lord's superintendent at the Gloucester, had missed some sheep. On the morning of the 16th he, with some other parties, went in search of them. While passing a native camp they saw the aborigines sitting round the fire, and very deliberately roasting some mutton. Mr. John Ashworth called to the party to surround the blacks to make prisoners of them, but they started immediately. The ground was very rough and broken, and Mr. Ashworth putting his horse to speed, he stumbled, and Mr. A. was thrown on his forehead. He was picked up immediately, and medical aid sent for, but on the  21st he died, deeply regretted by all who knew him. He was in the bloom of life. I should have mentioned that previous to the party going in search, the shepherd who had the sheep in charge had come on the blacks while slaughtering them when they threatened to kill him unless he promised he would say nothing of it.'
