Hi Maggie
I have looked at the censuses but cannot find a George. I wonder if he could possibly be a grandson? When did John b 1836 die?
There does seem to be other children to John and Sarah.
In
1891 they are in Fore Down, St Cleer, Cornwall
John, 55 and Sarah 54 have these children
Harriet 30
Thomas 26
William 22
Rachel 18 dau
Sally 13 dau
all children are single.
I can't see Rachel or Sally in the 1881 census

Here's a possible marriage for William born 1869
William Orchard =
Christiana PenfoldMar q 1898
St Austell Cornwall
GUESS WHAT?? ...
Christiana Penfold is my Great grandfather , William Penfold, his SISTER!!
they are both the children of Thomas Penfold(1841) who married Sophia Orchard (b 1846)
