Four children have been found: Humfrey, baptised 20 December 1597 at Uxbridge; Elizabeth baptised 9 December 1599 at Hillingdon, and buried there 2 April 1604; Dorathia, born at Hillingdon, but baptised at Uxbridge 26 December 1602 and buried at Hillingdon 27 March 1603; and William, baptised at Hillingdon 13 May 1604 and buried there 6 days later.
