Margaret Brown "Increasingly eccentric," and her later life

Hi y'all
In my copy of "Titanic: An Illustrated History," it was said that Molly became more eccentric. In what ways was she becoming increasingly eccentric?

Later in life her husband (second husband?) died, and her kids were at odds with her about his money. Who got the money, and what happened?

In 1932 she died from a stroke, was she in poor health?

Thanks!
