I suppose you already have this from British History Online site:
Petty Sessions (Ireland) Act, 1851, 14 & 15 Vict., cap. 93. (Form Ad.) Solemn Declaration.
I, John Kinkead, of Broharris, do solemnly and sincerely declare, that I remember my father holding about 18 acres in Ballykelly, 10 of which were under lease from the Beresfords, "middlemen holding under " the Company of Fishmongers." In 1820 the Fishmongers came into possession of the estate and compelled my father to relinquish his lease. The boundaries of the farms were then straightened, and, as a consequence, my father lost his holding, but got instead a few years after a farm in Ballyking townland, which was previously held by a man named Wright, who had to leave not being able to pay the rent.
I succeeded to my present holding through my uncle not being able to pay the rackrent imposed by the Company after they came into possession. The rent was raised from 10s. to 2l. 2s. per plantation acre. I never could have paid this rent from the resources of the farm, but did so from moneys earned at road making and boating shells for sale as manure. I reclaimed three acres of bog land on this farm without any aid from the Company. I believe all the land in this part was raised in the same rate as this farm. Of a number of tenants I remember Jack Creswell, Hamilton, Irwin, Andrew Grey, and Robert Cowan having to quit their farms owing to excessive rents, they being industrious men. Distraints for rent were very frequent.
And I make this solemn declaration conscientiously believing the same to be true, and by virtue of the provisions of an Act passed in the sixth year of the reign of his late Majesty King William the Fourth, chapter sixty-two, for the Abolition of unnecessary Oaths.
(Signed) John Kinkead.
Made and subscribed before me this eighth day of July in the year eighteen hundred and eighty.
(Signed) Theobald M. Bryson, J.P.,
Justice of said county of Londonderry.
