Flax was grown in West Cork in the 18th and early 19th century and its growth was promoted by landowners including Lord Bandon and the Earl of Bantry. There are numerous references to linen weavers in the period. See re 1749 and Cox in Dunmanway:

It underwent a revival during World War 1 and later World War 2. These articles are from the Adrdfield/Rathbarry JournalNo. 1 of 1998/9 and Roscarbery Past and Present Vol 5 2003.

In Bennet’s History of Bandon he refers to Sir Richard Cox’s efforts to develop flax growing and linen in Dunmanway in the early 18th century. The memories of William Jennings 1837-1922 who went to Australia refer to his longing for the Flax Mills on the River Bandon in Dunmanway:

Genealogy Chart of James Gallwey, Outlawed in 1690 and Mary O’Mullane, including French Branch descended from Andrew Gallwey born Enniskeane, Co. Cork, 1717, owner of Chateau and Estate at Turbily, improver of Breton Agriculture, host to Arthur Young, son officer in American War of Independence.

The Enniskeane Galweys were Land Agents including to the Dunmanway Shouldhams in the mid 18th century.  The Shouldhams were half McCathy being descended from a McCarthy heiress on the female line.

This is further evidence of the extraordinary spread of the Gallwey/Galway family. They had been prominent Cork Merchants since 13th century and the later family probably built on these links.  Andrew’s father Henry was a Bantry Merchant probably in the Pilchard business.  This had extensive Iberian links as witnessed by the 90 year old Mr. Young’s evidence to a Parliamentary Enquiry in Bantry in 1836 when he testified as to the Young families losses…

Dereenlomane Barytes Mine

This was originally worked as a copper mine by the Rev. Traill of Schull, assisted by Captain William Thomas in 1840 and they sold 19 tons of copper.  They discovered barytes or barium sulphate, a heavy white mineral, used for paint, papermaking for which in the 1850s there was a limited market.  An early use was by Josiah Wedgewood in the making of pottery.  In 1863 Captain Thomas was chartering boats c 160 tons and shipping the barytes to Messrs Martyn Dennis Liverpool and around 150 people were employed.  That year there was a serious flood which resulted in the mine being non operational for a period.  In 1867 the mine at what was described as Cahirolickaney Mountain was inaccessible and Captain Thomas built a road from the mine to the Dunbeacon Road nearly a mile long in three weeks.  It was marked by a celebration…
