Lewknor’s grandfather was a younger son from a prominent Sussex family seated at Tangmere near Chichester. The latter, abandoning the crypto-Catholicism of his family, became a successful lawyer, acquiring extensive estates in West Sussex including the manor of West Dean, and sitting in six Elizabethan Parliaments for Chichester.
Lewknor inherited his grandfather’s estates in 1616, and was returned at the next opportunity, in 1621, for Midhurst, six miles from West Dean, where his family had a significant interest. He was mentioned only once in the surviving records of the third Jacobean Parliament, on 30 Apr., when he received leave to depart into the country ‘for some time’ to recover his health.
Lewknor made his will on 8 Apr. 1635, bequeathing ‘in the pious remembrance of mine ancestors’ £100 for converting the funeral monument his grandfather had erected for his wife into a general family memorial. He died on 27 May 1635, aged 46, and was buried at West Dean. In accordance with his wishes his widow, brother Christopher and two brothers-in-law purchased his son’s wardship for £800. The latter sat for Midhurst from 1661 until his death in 1669.
