S. C. Hall, The Stately Homes of England
“ Sir John Vernon, Knt., married Helen, daughter and co-heiress of John Montgomery, of Sudbury, in Derbyshire, with whom he received the Sudbury and other estates, and thus founded the family of Lords Vernon. He was one of the King’s Council in Wales, and Custos Rotulorum of Derbyshire, and dying in 1540, was buried at Clifton Camville. He was succeeded by his son, Henry Vernon, who, in his turn, was succeeded by his son, John Vernon, who married Mary, widow of Walter Vernon, of Houndhill, and daughter of Sir Edward Littleton, of Pillaton Hall, by whom, however, he had no issue. ”
