It is possible that this MP came from the important Lincolnshire family of Copledyke, which produced the shire knight Sir John Copledyke† (d.1408) and in the 1430s held land in that county worth at least 100 marks a year.
Supplies for the garrison of Le Crotoy were shipped out from England through Winchelsea, and naturally enough, Copledyke formed an association with the barons of that Port. He himself owned a ship, the Katherine of Winchelsea, which was used along with vessels belonging to Bourgchier to help convey the entourage of Henry VI’s new queen Margaret of Anjou across the Channel from France in the spring of 1445.
Copledyke was returned by Winchelsea to the Parliament which met less than a year later, in November 1450, in the wake of Cade’s rebellion and the collapse of English rule in Normandy. He brought to the Commons first-hand experience of the state of affairs across the Channel, and perhaps also a predisposition to support the duke of York (Bourgchier’s brother-in-law) and other critics of the Lancastrian government. It seems likely that he complied with the statutory qualifications for election to Parliament as resident in Winchelsea, for in the following March he claimed exemption from paying parliamentary subsidies on his moveable goods at Guestling, as barons of the Port were entitled to do.
From that time on Copledyke regularly served on ad hoc royal commissions in Winchelsea and the Cinque Ports generally. The patronage of his former commander continued to play a part in his career. When Bourgchier was made treasurer of England following the Yorkist victory at St. Albans in 1455, he used his warrant to promote Copledyke as customer at Chichester and the other Sussex ports.
Nothing certain can be deduced about Copledyke’s political views from the royal pardon he obtained in June 1458,
It was also in the first year of the new reign that Copludyke moved from Winchelsea to Sandwich. He last represented the former Port at a Brodhull in April 1460, and from January 1462 appeared there instead as a delegate from the latter. This was the meeting of the Brodhull held during the recess of Edward IV’s first Parliament, in which Copledyke sat in the Commons for his new home town. He went on to represent Sandwich in nine more Brodhulls.
In November 1464 the royal grant of the bailiffship of Winchelsea was extended to Copledyke’s son John, the two of them holding it henceforth in survivorship. They were exempted from the Act of Resumption passed in the Parliament which ended in March 1465.
Copuldyke last attended a Brodhull in July 1466.
