Career
Most of the Wittewrong family followed Jacques, who made a career as a public notary, and died in 1593. Jacob was a wealthy brewer. He was knighted in 1640, and then fought on the side of Parliament in the English Civil War as a colonel.
He was High Sheriff of Hertfordshire in 1658.
He bought land at Wheathampstead in 1649. He was created baronet in 1662, and in 1667 bought Stantonbury from Sir John Temple, where he built a mansion of which only a few traces are left.
He also owned Rothamsted Manor. The family had leased it from 1611, and purchased it in 1623, after which Sir John made many alterations.
