Fabulous news about Ethel's grave location, tempered a little with no sign of JBG, and I'm indebted to you for finding this for me.
We should be in the area around Monday 19th and will have three days there so I think that'll be ample time to find what I need, and I'll certainly be anxious to meet up with the Church Warden.
The 1943 death certificate, ordered and en route soon, will hopefully show John's last address, and I can take it from there to seek his final resting place if he proves not to be at Peaslake with Ethel.
These other Gardner names are worthy of a bit of research, though I can't see that they are a 'second family' for JBG............though after all this time I'm not discounting it!!! Maybe a subscription to Ancestry will be required after all to find THEIR parents names.
You're well named Dawn; you brought light where there was but darkness!
