Members of the Warnecamp family, which took its name from Warningcamp, a mile to the east of Arundel, represented the borough in at least six of the Parliaments assembled between 1334 and 1380. One of them, Thomas Warnecamp† (three times an MP), held office as coroner of Arundel in the period 1361-91, and as deputy to the earl of Arundel’s steward in the rape of Chichester in 1390-2.
William is first recorded in September 1417 when a jury giving evidence before royal commissioners presented that he and a number of other men from Arundel had on the night of 4 Jan. that year broken down the bridge which had recently been built across the river Arun at Littlehampton, and removed timber worth as much as £40. On being brought before the King’s bench eight years later to answer the charge, Warnecamp and the rest explained that the wooden structures of the bridge had impeded the passage of boats bringing merchandise and victuals to Arundel from the coast, and that on the night in question, being prevented from sailing their boats up river, and in danger of capsizing, they had removed the posts and stakes to clear the waterway. However, they denied stealing them; they had merely placed them on the bank. The defendants were eventually acquitted, but not until 1431.
In December 1421 Warnecamp had served as a juror at Chichester providing information about the landed possessions of Arundel’s recently-deceased lord, John, Lord Arundel and Mautravers, and he did likewise at Arundel in August 1423 for the post mortem on the late Earl Thomas’s sister Margaret, wife of Sir Roland Lenthall.
Warnecamp himself was not necessarily always law-abiding. In Michaelmas term 1432 he had been sued in the common pleas by the prior of Tortington for illegal detention of a bond, a matter which the prior subsequently brought to the attention of the court of Chancery, then alleging that Warnecamp had conspired to defraud him of the sum of £20.
