In the 1841, I've found a William and Mary Browning living in Sandwich but William is a labourer.
I'll give the details, just in case:
St Peter, Sandwich
HO107/494/16/17/27
Browning
William, 55, labourer
Mary, 50
Ann, 15
All b. Kent

Hi Chris
I think you missed my posting - I'd already found them
I think if I were you I'd put up a request on the Kent board for a possible baptism of George in Sandwich circa 1821
There is an OPC for Kent but it doesn't look as if the baptisms are up for St Peter, St Clement or St Mary, Sandwich:

I am confused now......
I have found a possible 1st marriage for George Browning on 23 Aug 1848 to Mary Mills in East Ashford, Kent as well as a death for a Mary Browning in Q1 1851 in Bridge Kent which could fit. Using Ancestry, the record for Mary then links to an 1851 census record for Kent/Whitstable. On this census record as well as a George (with the right year of birth) and Mary Browning.
-Is it possible for someone to appear on the 1851 census if they died in Q1 1851 (when was the census taken?)
-"George" is shown as a labourer but we know he went on to become an Excise Inspector for the Revenue. Is such a career move feasible?
-also, if you look at the 1851 census there is a lodger, Henry Maxted. George Browning's aunt married Francis Maxted
So in some ways the above seems possible but also the 1851 for Upper Swinford fits so perfectly.
