Coningsby’s grandfather, a younger son, acquired North Mimms in 1530.
Coningsby was elected to represent Hertfordshire in the 1614 Parliament. On the first day of business, 8 Apr., he was named to the privileges committee and to consider the extension, revival or repeal of statutes.
Coningsby drew up his will on 14 Mar. 1616, by which time he was ‘sick in body’, leaving his principal estate to his second wife. His eldest son Francis was to receive an annual allowance of £150 during her lifetime if he married in accordance with the wishes of six trustees, including Sir John Luke* and Sir John Boteler*.
