By 1166 Ashburnham’s ancestors were already the principal landowners in the Sussex parish from which they took their name,
Ashburnham himself has to be distinguished from a cousin of the Broomham branch, who was knighted in 1625 for long and faithful service to the Electress Palatine.
Ashburnham was sent to The Hague in March 1627 with a personal assurance of support for the exiled Palatines. Three months later he accompanied Buckingham and the English army to the Ile de Ré and, though not a military man, helped to rally the landing party after it recoiled on being charged by French cavalry.
Following the retreat from Ré the Venetian ambassador in France reported, incorrectly, that Ashburnham had been captured.
After the prorogation Ashburnham was granted the estate forfeited by the murderer Sir William Withypoll*.
Ashburnham took no known part in the 1629 session, although he benefited from the fine imposed on Walter Long*.
