William Alcock, illegitimate son of Mary Alcock, was christened at Duffield, Derbyshire, on 2 June 1728.[1] His mother subsequently married Thomas Slater, on 14 April 1730,[2] and although Thomas acknowledged William as his adopted son, it is unclear whether he was the natural father - see discussion by the Slater Study Group in references below.

He married Elizabeth (Fox?), and died on 10 August 1782.[3]
