Sorry, my error. 1841 census records for the Paddington area are not available. We have them Henry and Eliza Damry in 1851 HO107/1467. Eliza is then shown as 50 but with a 3 year old child.
Eliza died in 1853.
Thamar Nethway married William Fitch at Wanstead 11 Jun 1823 [IGI]. We would not have associated these two ladies for sure but she and her husband were both dead by 1851 leaving their eldest daughter, Charlotte to mother various children. Charlotte and a younger sister appear with the Damrys at various times. Charlotte m. Smallman and Charlotte Smallman, her daughter, also guests with a Damary on one occasion.
I have not been able to find Thamar anywhere else but from the children's ages we know she was alive in 1847/8 but dead by 1851.
Due to the variety of spellings - Eliza, Elizabeth, Nathway, Nethway, Damry, Demery, Demery, Damary and Samuel Henry becoming Henry Samuel in later life it is quite hard to get to grips with this family at this period. It has prevented me from putting their documents in a tidy way.
