(Sigh!

) Thank you very, very much for looking! I really do appreciate it!
The wretched woman lived in the East End of London all her married life and most of her widowhood (goodness knows where at the end!) I can't find a death or a remarriage for her, and as one and possibly two of her sons were in Hong Kong and Taiwan, I thought she might have gone out to live with one of them. Obviously beamed up by Scotty!!

Anyway, thank you for at least eliminating that possibility. Back to the drawing boards!
