Foster, William Anthony Sutcliffe, Hon
Lieutenant William Foster of the 80th Regiment of Foot arrived in Berrima on October August 1838 as Assistant Engineer and Superintendent of Convicts at a salary of £109/10/-. He replaced Lieutenant Horatio Gulston who had been in Berrima for only three months. Foster was to be the last of the officers in charge of the stockade as it was disbanded later that year when the building of the courthouse and gaol were more or less complete.
Foster was the third son of Thomas Henry, Viscount and Baron Oriel of Collon County Louth. His grandfather, the first Baron, had been very active in Irish politics. Contingents of his regiment had arrived accompanying convict ships from November 1834 and regiment left for India in August 1844.
