Zheng Keshuang
When the Ming dynasty fell and the Qing dynasty took over, the Qing Emperors granted a Ming descendant the title Marquis of Extended Grace and gave him a stipend to perform sacrifices to his ancestors, the Ming Emperors at the Ming Imperial Tombs. The Qing granted Zheng Keshuang of the Kingdom of Tungning the title of "Duke of Haicheng" (海澄公) after he surrendered to the Qing.
