Her brother, Betty's elder son John Humphreys, adds:
"A librarian colleague ... had worked at Mum's old girls school, which still exists (I think). She told me that the library's stock had been little modernised since Mum's time, but that would have been about 20 years ago. As far as I can remember, Mum and Foi did not attend schools in the Lake District (as Anne says). The family developed the routine of going down to London where they rented a house for some time (3 months?) after Christmas, and there the girls began to go to this school, returning home with the family when the time came. Eventually they asked to stay there as boarders.I don't know about flower arranging, but I assume the curriculum was directed to the needs of well-brought-up young ladies. English, certainly (writing letters to each other was an essential accomplishment). A smattering of simple maths, and very likely French. It would be nice to think that some of the rest was both intellectual and practical, but I doubt it. Wikipedia's list of private schools in Kensington & Chelsea includes one called 'Queen's Gate', founded in 1891 and with alumni including Camilla, and Nigella Lawson. Sounds classy enough. But I simply can't remember the name for sure."
