The Culpepers first appeared in the Medway valley in the thirteenth century, and supplied a knight of the shire for Kent in 1361. ‘Men of blood and iron’, or in less picturesque language, soldiers and ironmasters, they ‘spread themselves in different branches over the whole face of the county’, and across the border into Sussex. Culpeper, although a younger son, inherited his father’s favoured seat at Greenway Court in 1591. He retained chambers at the Middle Temple until 1627, though he was never called to the bar, and shared with Sir Dudley Digges* an interest in the North-West Passage Company. More advisedly, sometime after 1612 he purchased a lease of ‘all post-fines and issues of greenwax of the duchy of Lancaster within certain counties’ from the executors of Sir Roger Aston*.
In 1614 Culpeper was returned for Chippenham in a contested election, on the recommendation of his neighbour Sir Francis Fane*.
Culpeper was returned to the 1628-9 Parliament for Tewkesbury, presumably on the recommendation of Digges, who had represented the borough since its enfranchisement in 1610. His own connections in the neighbourhood included the marriages of two of his first cousins to Sir Samuel* and Sir William Sandys.
In 1632 Culpeper purchased Leeds Castle, Kent from the heirs of Sir John Smythe II*, and settled it on his sons.
