莫登庸
Trịnh Kiểm claimed descent from Trịnh Khả, who was one of the top aides of Lê Lợi and later became the top official during the reign of child-king Lê Nhân Tông. His relationship to the General Trịnh who defeated a rebel army in 1511 and then led a rebellion of his own in 1517 is unknown. Also unknown is his relationship to Trịnh Duy Dai and Trịnh Duy Sản (two of the leaders of the first revolt against Mạc Đăng Dung).
