Lewknor’s father died when he was barely five years old and his mother subsequently married Sir William Oglander. A younger son, he was bequeathed an annuity of £20 from his grandfather, Sir Richard Lewknor†, the chief justice of Chester, who died in 1616.
In 1628 Lewknor was returned for Midhurst, presumably at the nomination of his brother Richard, the borough’s representative in the previous four parliaments but now elected for Sussex. It would probably be easy to confuse both men in the records of the third Caroline Parliament were it not for the fact that neither was prominent. Both were entitled to sit on the committee to consider the saltpetre bill, to which the knights and burgesses of Sussex were added on 9 June, and one or other reported from the committee six days later on the abuses of the saltpetremen.
one of the House of Commons hath affirmed that his grace did speak these words at his own table, viz. Tush! it makes no matter what the Commons or Parliament doth; for without my leave and authority they shall not be able to touch the hair of a dog.
On the following day he revealed that Lewknor had admitted to spreading the story, having heard of the duke’s alleged outburst from a witness who he refused to name. The Lords, fearful of a privileges clash with the Lower House, decided to respite further proceedings until the subsidy bill had been passed, and the incident seems to have been quietly forgotten. Lewknor left no further trace on the records of the Parliament.
By the early 1630s Lewknor was recorder of Chichester where, despite holding diocesan offices, he put himself forward as the champion of city jurisdiction over the Cathedral close.
