Alan,
In 1926 the management of Settinglingstones was taken over by George Trestrail on his return from India. George was the son of possibly the last of the great Cornish mine engineers, Nicholas Trestrail of Redruth. Regarding the deposit of witherite at Settlingstones, see his article in the Transactions of the IMM, vol 40, 1930-31 entitled 'The
witherite deposit of the Settlingstone mine, Northumberland'.
