Hi again Paul,
What a pity you don't have anything else. Well I suspose you could do it the hard way. You know when Edward died, if you got a copy of his death certificate, it will have the name of the informant, which if you are really lucky could be either his wife, a child or a sibling. Any of these names would be helpful to you in the following ways:
- a wife's name would help in looking for a marriage certificate - which would have the name of Edward's father
- a child's name would help in looking for the birth of the child, and the birth certificate would give the wifes name (and maiden name) and then you could follow the step above
- a siblings name would help in tracing the family on the 1901 census.
Sorry not to have been of more help, it's a bit unfortunate when you have a reasonably common name in London. Let me know if I can be of any more help.
