Christopher Hatton, 1st Baron Hatton

He was a noted antiquarian and compiled, together with William Dugdale and others, the "Book of Seals", a volume of 529 medieval charters, of which 240 are reproduced in facsimiles drawn by a highly talented draftsman.

Hatton entered Parliament as MP for Peterborough in 1625, though legally too young to sit, and Clitheroe in that of 1626.

In 1643 he was created Baron Hatton of Kirby; and, acting as comptroller of the royal household, he represented the king during the negotiations at Uxbridge in 1645.

Many of Jeffreys's letters are preserved in the Hatton-Finch correspondence; they cover a period of nearly forty years.

[1] He married at Hackney, Middlesex, on 8 May 1630, Elizabeth (died 1672), eldest daughter and coheiress of Sir Charles Montagu, of Boughton, Northamptonshire.
