Yes I agree with you Joburg.- this seems to be them.
And with that surname in mind I've also found mum and dad in 1851

HO107/1696 folio 287 page 8
At Shooting off (yes it DOES say that

) Staines Middx
But both of them transcribed as Geever
Abel Yewer 56 head farm labourer b Buckinghamshire ???layer??? Can't read it sorry
Harriett Yewer 52 b Stoke Bucks
Jane Sherwood 2 (grnd?) child b Staines
Caroline Shieves or Shields? 1 (grnd?) child b Staines
The writing is awfully spidery and difficult to read.
Second opinions required please

Hope this helps
Carol
