Hi, Calibra, can't find an obvious Malpas baptism for John. However given that his wife Elizabeth states born Whitchurch I looked on familysearch and there is a marriage for a John Maddocks to an Elizabeth Harrison on 31.12.1846 in Whitchurch. This states his fathers name as John and hers as Thomas.
Also a longshot there is a baptism of a John Maddocks in Malpas on 8.6.1822 with a father John and mother Elizabeth, John senior is a labourer and their residence is Bickley. This is from the Cheshire Parish Registers.
