Something is off with that 1851 Census;
I have on Anc;
George Palmer 37
Grace Palmer 35
George Palmer 12
John Palmer 4
Edwin Palmer 10
Willm Palmer 9
James Palmer 5
Probert Palmer 3
Alfred Palmer 2
Martha Palmer 20
The way it is ordered it would appear John is older than 4.
The image has lines through it so is hard to read.
So likely John is 11.
John may be with his Grandparents in 1841;
James Palmer 55 Sawyer
Ann Palmer 55
Jane Palmer 19
John Palmer 14
MARTHA Palmer 12****
JOHN Palmer 1********
Martha Cutter 20

Trish I agree with you it definitely looks as if John Palmer's age
should read 11 and not 4PALMER, JOHN
