Good advice from Sandy there as always

These are the rest of William and Susanna's children at Denford in the PRs:
Elizabeth bapt 3 April 1774
Rebecca bapt 6 Jun 1779 bur 9 Nov 1780
Rebeccah bapt 21 Sept 1783
There was a transcript for this period and it showed that Elizabeth's baptism was the first mention of Reynolds in the parish of Denford.
This could be a possible marriage for the parents at Cranford St John which is only 3 or 4 miles from Denford:
William Rennals otp, labourer and Susanna Maycock otp, spinster married 25 Aug 1771.
Witnesses John Gray and James (Mills?)
This couple had no children baptised at Cranford St John.
Unfortunately they don't seem to have been baptised there themselves either

Back to Denford:
Susannah the wife of William Reynolds pauper bur 13 Jan 1794
Which fits nicely with his remarriage to Ann the next year.
Ann wife of William Reynolds bur 30 Dec 1800
William Reynolds labourer bur 7 Apr 1807
Hope that all makes sense!
