Just recently did some research on the Prosser family and have read the thread that you started 2010. I wonder, did you ever find out where Lizzie disappeared to. I concluded the marriage failed - John off to B-i-Law's farm in Hay. Kids farmed out to the couple in St Briavels. Then I found John Prosser in Hay Mental Hospital on the 1939 Census.

I believe Daisy Mary Prosser was adopted some time between the 1911 census and 1915 by Albert and Dorothy Addis from Clearwell, Coleford, FoD. Intrigued to know the connection between these 2 families (if any).
