I have now found the origin of my great-great-aunt's name.
She was LOUISA HUBBERT QUINTRELL.
Louisa Ann Ellis married Nathaniel Hubbert in 1823 at Finsbury by licence.
So far I have nine children for the couple, but the first one I found was in 1829. He was William Henry Hubbert and lived until 1901.
The family moved to Portsea, where Louisa Hubbert would have met Jane Wood, grandmother of Louisa Hubbert Quintrell. Jane Wood's father Newbourn Wood and Nathaniel Hubbert both came from Lincolnshire and were both drapers.
Six of the other children died in infancy or young.
I can't find any records, apart from christening records and the 1841 census, for Robert Hubbert, baptised in 1834 at St John's, Portsea, and Mary Hubbert, whose only record is the 1841 Census.

Louisa is absent and in the household is Harriet Beaumont, aged 30. The Hubberts had a son named George Beaumont Hubbert in 1835 and a daughter Harriet Beaumont Hubbert in 1837. No baptisms for them, just their burials.
How is Harriet Beaumont related to them?
