An old Castletown merchant family intertwined with the Moores, Christians, and Quayles. John Taubman was George Moore's political lieutenant and successor as Speaker of the Keys. His commercial interests were as extensive as Moore's own. It was Taubman who accused John Quayle of deception — complaining that merchants had been 'amused and even assured' the Duke would not sell, the word 'amused' carrying its older meaning: deceived. Taubman held pre-Revestment stock and profited from shortages after the trade collapsed. Three years after the Revestment, he was writing operational orders routing a captain to Barcelona for brandy, approaching the Island 'in the dark of the Evening or night.' His son Major John Taubman married Dorothy Christian of Milntown — connecting the family to the Christians who had been providing Deemsters since 1408. As Speaker, Major Taubman was directly related to twelve of the other twenty-four Keys members. Captain Taubman recommended Fletcher Christian to Bligh in 1784.
