George and Isabella had seven children
James 1834
Esther 1836
Claudius 1843
Christian 1844
George 1848
Isabella 1831
Elizabeth 1837
All but Elizabeth are on the 1851 census, as is a nephew John Quine 11

In 1861 George is a widower, Elizabeth and George are with him as is Isabella Corlett a granddaughter and Esther is a servant.

In 1871 Esther is alone wit her father.

The IGI has a 11 November 1866 christening for Isabella Jane Quayle in Lezayre, daughter of Esther Quayle.
There is no obvious Isabella in the 1871 or 1881 census.

Esther does not appear in 1881, so she may have married.
Possibly Isabella is there, but with her father's name.
