I’m glad it seems as though you’ve solved the riddle, Annie. It is sad to think of people in unmarked, unvisited graves. It’s only in recent years I discovered where my grandmother is buried, along with one of her children. Like you, I’d spend money on a gravestone if I had enough spare £££. It was an emotional experience when I visited the grave, just a small metal plate with a number on it to show where it is.
I absolutely did not mean to hijack your thread with my own query, so I’m sorry about that!
Genealogy is one of those topics that if you know someone else is interested, you just want to share stories.
Thank you for all the hints about M George though I don’t think any of them fits the picture. The family weren’t on the 1911 Census because they had just left the UK onboard a ship bound for S Africa, which is where they lived (She was S African, my grandfather was BRitish) . The ship manifest only has the parents and their four children aged between 12 years and six weeks of age and I can account for all those children.
It wasn’t a DIL, either, as the older son wasn’t married. I doubt it was an unofficial adoption, either, because the poor woman was widowed en route to the UK from SA six months later and left with four children to care for. She never returned to SA or saw her family again, as far as I can tell.
Her late husband’s family seem to have helped her out in various ways, housing her, but when she died she only left £38 in her estate. My dad was unofficially adopted by a paternal aunt.
