Hi Heather,
I think you have more or less cracked it, thankyou. The first baptism record I looked at for Edward was illegible for father's occupation but the one shown on FMP for 1739 is quite clear and shows his occupation as cutler so that does rule out William and Hannah as his parents.

The marriage you found in 1739 for William and Mary Ridge would fit Edward's birth and his occupation fits too. According to FMP William was baptised in 1715 father's name William and Mary Ridge's baptism was in 1718, father's name Thomas a mason. I don't have either of these two in my tree so that's where the confusion has arisen. William the labourer died in Dec.1750 and Hannah his wife does appear to have died in 1740 (thought it might have been in childbirth!)

Think we might be able to put this to bed now, thankyou all for your input, it's been very helpful.
