Nonsuch, as reported by Brian Shelley, means "without rival" (Without Rival, by Brian Shelley and Mary Beaucock Fryer, 1995. Wishbone Publishing Co. Willowdale). The class was named after the Nonsuch of the Hudson's Bay Company that first sailed in 1968. That vessel was named after Baroness Nonsuch of Nonsuch Park, Surrey, England, who was the mother of King Charles II's two natural sons. The Baroness also bore the illegitimate daughter of John Churchill, who was the First Duke of Malborough, and became governor of the Hudson's Bay company in 1685.
