Christopher,
Here are some people without the 'g' in their name who were around in 1851.
CHALLENER Hannah Unmarried 57 Paulton / Dunkerton
CHALLENER ???Fanny Servant 32 Bedminster, Bristol / Bedminster
CHALLENOR Jane Widow/er 58 Cheltenham / Cheltenham
CHALLENOR James 25 Carver & Gilder Cheltenham / Cheltenham
CHALLONER ? / CHALLENGER / CHANCELLOR 65 Farmer 38 Acres Chew Magna, Som /
Chew Magna
CHALLONER George Lodger 87 or 89 Retired Warrener ?? Clutton, Som. / Compton
Bishop
CHALLONER Thomas 44 Teacher of Rhetoric Middlesex Westminster / Bedminster
CHALONER Charlotte Niece 12 Cheltenham / Cheltenham
Where it says, for example, Paulton / Dunkerton, that means that the person
stated that they were born in Paulton, but were located in Dunkerton when
the 1851 Census was taken.
Regards,
-- Andy.
