Lady Anne Carteret married Sir Nicholas Slanning, K.B., on November 4, 1662. He became a Cup-bearer to Queen Catherine of Braganza 1663-?d., and at this time holds some posts in Devon and Cornwall (being a West Country lad). They had one daughter before Lady Anne dies in 1668.
She is described as being “a pious and good-humored lady, connected him with one of the most powerful figures in the Clarendon administration, and earned him a baronetcy, a minor post at Court, and the grant of the governorship of Pendennis in reversion to his step-father.” He liked chemistry, became a fellow of the Royal Society, and discovered a cheaper and better way of melting, forging, and refining iron and other metals with turf and peat, to the great preservation of wood and timber -- so he must have known Pepys.
