Sir Jacob Downing, 4th Baronet
Sir Jacob Garrard Downing, 4th Baronet MP (c. 1717 – 6 February 1764) was an English baronet and politician. He was the grandson of Sir George Downing, 1st Baronet, namesake of Downing Street; and cousin and heir of Sir George Downing, 3rd Baronet, whose Gamlingay estate would eventually establish Downing College, Cambridge despite illegal attempts by Jacob and his widow to prevent the university from receiving the estate.
