Going back to the original topic about the actual home.
There are a few topics on Rootschat about births there and subsequent adoptions.
including this of a child whose parents were married at the time of conception.
http://www.rootschat.com/forum/index.php?topic=435225.msg4149503#msg4149503Internet searching suggests that this was a mother & baby home as well as a nursing home for geriatric patients.
It was privately run and no records exist.
A report on the Wellcome Library site
http://wellcomelibrary.org/moh/report/b19885957/57#?c=0&m=0&s=0&cv=57&z=-0.514%2C0.5277%2C1.9218%2C0.7502states that at a much later date, there were only 2 maternity beds, the rest for the chronically sick.
The address is easily found on the 1939 register.
It is hard to establish what relationships were and the scenarios causing the names to be listed there but there were a couple of young single women and interestingly a number of redacted lines but 2 unredacted were shown as later adoptions.
In the days before the welfare state, I would imagine a nursing home approached by someone willing to pay for their confinement might be a better option for the mother than entering the workhouse or maybe a difficult or untimely labour urgently required the assistance of those at the address.
George Oliver & Emma Walker Eldridge, the proprietors, were there from 1934 according to the electoral registers with Mrs Eldridge being a State Registered Nurse and Certified Midwife still listed in the 1960's.
After 1948 but before the 1960's, the Eldridge's might have turned the address into more of a maternity home for unmarried mothers possibly receiving their funding for this service from the state. The lack of records doesn't prove or disprove this suggestion. Maybe they were also receiving fees for their adoption services.
Other internet searches reveal that Hackney Social Services are unable to help further.
