Hi, thanks for the inputs. I also realised that St Andrews Lamesley and St Cuthberts CLS are both Anglican, so there is that at least. There was a period about 1740s when Lamesley was in disrepair apparently and it was rebuilt in about 1759 (I think). So some bouncing around may be OK.
I still cannot tie William Wind marriage to Cow Close, but it seems "possible".
Irritating but another William Wind married an Ann Hopper 1750 in Witton Gilbert, C Durham. Its further away and I dont think it links to Lamesley....
EDIT
I found that the Witton Gilbert marriage says that both are from Kimblesworth, so two different Williams, they were married at St. Michaels, which is Anglican in 1750, William (of Kimblesworth) to Ann Hopper (of Kimblesworth) according to RecordsOnline. So William and Ann are still possibilities
