I am fascinated by your research. I have been researching my wife's family line for her for some time and have not devoted much time at all to my own line.
My father was George William Charles Baldwin born in 1912 (ish) his father was William John Baldwin and he had a brother John William Baldwin. Their father was William John Baldwin and his wife was Jan ?.
As you can see I have very little except the family mythology that the family originally came from Cirencester to serve as Stone Masons on St Paul's Cathedral in London.
The family I have listed lived in the West Ham area of East London, Which of course was originally in Essex.
If you have any connection with these I would be delighted to hear from you.
