It's probably not fair of me to answer as I know your thought processes too well & we've probably both just read Katie Roiphe's Uncommon Arrangements. Bertrand's sister-in-law was Elizabeth Von Arnim & her cousin was Katherine Mansfield & KM & her husband spent some time living with DHL & Frieda in Cornwall during WWI.
Ok - I obviously cannot compete with Lyn there, but I was going to go with:Edith Finch was Bertrand Russell's fourth wife, and by a huge stretch of the imagination, she probably knew Katherine Mansfield, who obviously knew DHL ...... but I think Lyn's is a better fit!
BloomingEccentricKind ofDrivel???Sorry, just joking because I can't get it :-)
I knew KM would be part of the answer but that was as far as I got.
