Listed as
Ampney Down in 1801 had a population of 279 (if you divide by 6 = approx 46 families) and a few years later had grown to 324 (approx 54).
As my x Grandad was a Carpenter & Wheelwright in the same Village - and from Ancestry Apprenticeships records - (1710-1811)
On the 4 Dec 1784 - at Down Ampney he had an Apprentice named Wm Green and on the 7 July 1788 his Apprentice was Thos SLY.
So records may exist to see who Stephen RICKETTS was apprenticed either on Ancestry or at the Gloucestershire Records Office
Our families probably worked together at some point.
