dear all,
thanks for your efforts and all the information, I shall work my way through everything

@ ColC
I have now also checked for other possible offspring of Joseph and Elizabeth:
i. Elizabeth Rogers, bap 19-05-1751, Old Meeting (Independent) Norwich
ii. Katherine Rogers, bap 16-08-1752, St Andrew, Norwich
iii. John Rogers, bap 05-11-1753, St Andrew, Norwich
iv. Richard Rogers, bap 08-10-1754, St Andrew, Norwich
v. Diana Anna Rogers, bap 30-11-1755, St Giles, Norwich
vi. Joseph Rogers, bap 16-01-1756/7, St Giles, Norwich
vii. Susanna Elizabeth Rogers, bap 27-08-1760, St Andrew, Norwich
( Susanna Elizabeth Rogers, burial 30-08-1760, St Andrew, Norwich)
i. Curious that the baptism takes place in an Old meeting house (Independent) .The actual baptism entry reads: ' Elizabeth daughter of Joseph and Elizabeth Rogers (of Wrentham) bap 19-05-1753. Wrentham being just accoss the border in Suffolk

v and vi. Not so sure, why the sudden move to another Church? St. Anrew doesnt look very far from St. Giles.
vii. I believe that Susanna and Elizabeth are one daughter with a double name, at least it looks that way on the actual baptism register with what looks like an Elizabeth being added between and above Susanna Rogers with an upside down v below between and below.

I like the 'John Harmer' name change theory. I have been nursing the idea that maybe Harmer Rogers was adopted and had something to do with the departed John Harmer, but was not very far with that. Anyway, as you say, the clue would be to see if 'John Harmer' is accounted for ! As of yet I have not looked at any of the other possible offspring of Joseph and Elizabeth, excepting Susanna Elizabeth, who didnt live for long.
Think I need to look at John Harmers family and try to put that together too

Thanks for the Dusty Docs reference, I do not know this site and hope to make good use of it in the future once I get the hang of it

@amondg
I had searched for Elizabeth Quintin or Quinton and had found only 2 candidates:
i. Elizabeth Quintin: parents Thomas and Margaret, baptised 29-01-1748, St Stephen, Norwich
ii. Elizabeth Quinton: parents John and Mary, baptised 15-09-1751, St Benedict, Norwich
burial Elizabeth Quinton, 25-08-1751? St Benedict, Norfolk

This was a far as I got, so the burial of ' Elizabeth Rogers nee Quinton is buried 17 February 1803 at Woodford age 49 -born circa 1755' Is something worth looking into with regard her origins
