Coningsby traced his ancestry back to the reign of Edward I, when Roger Coningsby, steward to the earl of Warwick, acquired manorial property in Warwickshire, which county his son John represented in the Parliament of 1344. The senior line remained firmly rooted in the west Midlands, with the head of the family seated at Neen Sollers in Shropshire.
Re-elected for Leominster in 1604, Coningsby seems to have been the chief agent in obtaining for the borough a new charter in 1605.
Coningsby was re-elected to Parliament in 1614, but his only committee appointment was to consider the bill to increase the powers of feodaries at the expense of escheators (14 May).
Coningsby died in 1616 and was buried at Docklow the day after his death.
