the wonderful first chap of S&S re the brother's wife talking him into dumping his DM and DSis's - a cracker.
JA makes the vital point that while men inherited cash as Head of Family, they also inherited responsibilities (ie their female relations) - which were all too easy to welch on - Mrs Reid's awful son in Jane Eyre does the same to his mother and sisters.
I swear this chapter is word-for-word what happened in Jane's life, as it happens. Her DF gave the family home and business to his eldest DS, who was married to a girl rather fond of the good life. Indeed, so fond was she of nice things that she nicked Jane's piano and cabinets on the grounds JA & her DM, who were now homeless, wouldn't have anywhere to put them. As SIL go, she was the tactful sort we see a lot of on MN.
Jane's DF died suddenly, leaving JA, DM and Cassandra pretty poor, homeless etc.
Jane's DB and SIL, now Head of Family, were duty bound to house and feed them. JA & Co were never invited back for so much as a sandwich.
When she died, JA was in a B&B up the road from her own family house - her SIL thawed enough to offer 'to send my carriage' for the dying Jane to see a doctor. Jane Austen said 'I bet she enjoyed doing that' - it had been Jane's own carriage. Then she died, comic timing pitch perfect to the last.
