Details Clementson had sailed from England to Sydney as Chief mate in a brig 'Elizabeth' commanded by a Captain Stewart. It came to New Zealand and whilst here, transported Te Rauparaha and his warrioursfrom Kapiti Island to the South Island in 1830. Later Clementson shipped as mate on the brig 'Bee' out of Hobart Town a charter to Lincoln Bill (William Cuthbert) an old convict. Clementson and Lincoln had a disagreement and he was put off the boat near Cloudy Bay. Clementson met up with another man called Ferguson and presently went aboard the boat belonging to Philip Tapsell. Philip offered him a job as a trader at Matamata which he accepted.
In about 1836-37, Clementson and Farrow who were both working for Tapsell left for Matata in a whaleboat for the purpose of consulting with Tapsell's agent White there. They were both drowned in the surf attempting to land at Matata.
