Carrigbuie, from George Bennett’s History of Bandon 1869
About five miles south-west of Bantry is the pretty little village of Carrigbuie. It is agreeably situated at the head of Dunmanus Bay–one of the great inlets from the Atlantic–and in a district where copper barytes, flags, and slate of superior quality, are to be found in abundance. The copper-mines in this locality are favorably known. The “south band,” which runs along the coast from Mizen-head to Roaring-water, has already produced copper-ore worth a hundred thousand pounds. The Bandon barytes mine has rewarded the energy and perserance of a Liverpool company with a yield of several thousands of tons. Flag quarries, which overhang the sea, produce flags of a fine buff co lour, and are represented as capable of being worked to great advantage; and the slate veins of Sea-lodge and Rossmore, already traced to a length of two miles, are found…

The Bandon estate recovered Durrus lands on the expiration of the Evanson’s lease c1850.  The estate extended from Crottees to Brahalish and included the village which the estate rebuilt c1850.
In the Bandon Estate papers there is a lease from Bernard to Charles and Nathaniel Evanson and Jeremy Cough(l)an (probably of Carrigmanus/Crookhaven their cousin) of lands at Gerhameen, Coller, Rathmore and Rosavanny for 31 years from the 30th October 1727.
The estate donated the site of the present Catholic church c1899.
In the late 19th century Lord Bandon used Durrus Court as a summer residence. The family maintained gamekeepers in areas such as Coomkeen, the Burke family.

The rental registers of the estate covering the Durrus lands from 1850 were rescued some years ago and are currently in the Cork Archives Institute but are awaiting restoration.

General Charles Vallancey Survey Report  1778

He was sent to Ireland to assist in a military survey, remained and became an authority on Irish antiquities.  
He fathered 44 children by three wives. He learnt Irish and became fluent in it.  Some of his theories are now regarded with a degree of scepticism.   He wrote a report on the West Cork area which should also hold true for Durrus at the period: ‘There was only one road between Cork and Bantry; you may now proceed by eight carriage roads beside several horse tracks branching off from these great roads, from Bantry the country is mountainous and from the high road has the appearance of being barren and very thinly populated; yet the valleys abound with, corn and potatoes and the mountains are covered with black cattle. In 1760, twenty years ago it was so thinly inhabited, an army of…
