The arms are those of Bankes impaling those of Dethick as borne by Sir John Bankes, born about 1627, although the arms differ slightly from those recorded in published accounts. He was M.P. for Maidstone 1654-1659, for Winchilsea 1677-1678, for Rochester 1679-1690, for Queenborough 1690-1695 and for Maidstone again 1695-1698. He was of Lincoln's Inn Fields and of Aylesford, Kent, which estate he purchased. He married, in or before 1657, Elizabeth, daughter of Sir John Dethick, sometime Lord Mayor of London. He was created a Baronet on August 22, 1661 and died, in his 72nd year, on October 31, 1699, when the Baronetcy beacame extinct. His only son, Caleb Bankes, who had been admitted Gray's Inn in 1674 had died in 1696, age 37. Of Sir John Bankes's two surviving daughters and co-heirs, Elizabeth, who inherited the Aylesford estate married, about 1677, Heneage Finch who, in 1713, was created Earl of Aylesford; Mary, the other daughter, married John Savile and died in 1740, age 82.
