J. Conway Walter, A History of Horncastle, from the earliest period to the present time
“ His brother Sir Robert also held high office and was made in 1603 Baron Cecil, in 1604 Viscount Cranbourne, in 1605 Earl of Salisbury. Thomas Cecil died Feb. 7, 1622, aged 80, and was buried in Westminster Abbey. He married 1st Dorothy, daughter of John Nevil, Lord Latimer, and 2nd, Frances, daughter of Lord Chandos. He was, doubtless, a man of large ideas and great ambition, his royal mistress was herself Lady of the manor of Horncastle, and Horncastle having thus been brought under his notice, he may have been too grasping in compassing his purposes. ”
