I found the best information ... and that wonderful Starkadder family tree chart ... at Wikipedia:
That's the place you will also find a list of Flora's solutions to the Starkadder problems. The novel ends when Flora, with the aid of her handbook The Higher Common Sense, has solved each character's problem. These solutions are:
Meriam: Flora introduces her to the concept of contraception.The future
Seth: Flora introduces him to a Hollywood film director, Earl P. Neck, who hires him as a screen idol.
Amos: Flora persuades him to buy a Ford van and become a travelling preacher. He loses interest in running the farm and hands it over to Reuben.
Elfine: Flora teaches her some social graces and dress sense so that Richard Hawk-Monitor falls in love with her.
Urk: forgets his desire for Elfine and marries Meriam.
Mr Mybug: falls in love with and marries Rennet.
Judith: Flora hires a psychoanalyst, Dr Müdel, who, over lunch, transfers Judith's obsession from Seth to himself until he can set her interest on old churches instead.
Ada: Flora uses a copy of Vogue magazine to tempt her to join the twentieth century, and spend some of her fortune on living the high life in Paris.
Adam: is given a job as cow-herd at Hautcouture Hall.
Graceless, Aimless, Feckless and Pointless: go with Adam to Hautcouture Hall.
Big Business: Flora lets him out into the sunlight.
Flora: marries Charles.
There's one other thing I noticed ... Stella Gibbons seems to have been trying to predict the future! If you remember that the novel was written in 1932, you would be surprised at some of what was there. I wrote this in my reading notes when I got to Chapter XII (12), my pages 140-141, and then page 177:
What's with the television in 1932? Especially a phone with a television? Stella Gibbons must have been trying to predict the future ... especially since she mentions "the Anglo-Nicaraguan wars of '46" as something in the past!The Wikipedia article mentions her use of air taxis. What sorts of things did YOU notice in the book?
