I know this is a long shot but nothing ventured, nothing gained. I have access to Canadian records but not UK records.
Since you are researching Davey, I have just this week found out that my aunt Freda Lewis, nee Davey, was born "somewhere in England" according to her son. Her birth date was July 10 1912. She came to Canada and married Prosser Lewis in North Vancouver, British Columbia. They later moved to Seattle, Washington.
Any chance you can help?
