1841/51 Census Lookup Please - Walker

[Carole4]

I am trying to find a
Thomas Walker abt.1799 Keysoe Farmer
Charlotte Walker abt 1800 Yelden

They married in Northants 1825
Charlotte's maiden name was York.

in 1861 they are found in  Ippollitts, Herts
by 1871 Charlotte has died and Thomas is found in
Hitchin  Herts.

I know it is a lot to ask, because I truly have
 no idea where or even if they are in Beds.
Thanks for any help!
Regards,
Carole

They are not in Ippolitts in 1851. Did they have any children which might help pin them down?

Thanks for trying David.
I do not know if they had children.
I do not think they did, as there are none with them on the 1861 census.
and in the 1871 the daughter of Charlotte's brother is living with Thomas,
as a Housekeeper.
