Baby Joseph must have not been expected to live, because he was baptised on the same day.
Shortly afterwards, he died.
In 1810, the burial of a Charlotte Mawbey took place at Christ Church, Southwark.
The father of the deceased child and mother was the son of the original Sir Joseph Mawbey who also bore the title of 'Sir'.
Chertsey is a very old English town on the banks of the River Thames.
It appears in the Domesday Book under a different spelling and was a Saxon stronghold.
Sir Joseph Mawbey and his wife Eliza lived in the neighbouring parish of Botleys.
There is a memorial to Eliza in the Anglican church at Chertsey where she was buried in the family vault.
