Hypothesis: That William GOULD, baptised in Stanton Drew, Somerset, on 30th December 1804, is the same person as the William GOULD who married Hannah Clarke in Chewton Mendip on 22nd May 1828.
Hereafter, the former will be referred to as William 1 and the latter as William 2.
Chart 1: Attempted Direct Proof (1) by date of birth
Chart 2: Attempted Direct Proof (2) by comparison of parent forenames with forenames of first male & female children
Chart 3: Attempted Counter Proof by date of birth
Conclusion: It seems likely, but no more than that, that William 1 and William 2 are the same person.
