How did Lizzie try to make her father happy as noted in the biography, You Want Women to Vote, Lizzie Stanton?

Judge Cady grieved the loss of his sons greatly, and Elizabeth wanted to make him happy. She was a girl, but Fritz says, "Still, perhaps she could make it up to her father if she became just as good as a boy, as smart and brave as Eleazar had been. So that's what she'd do. To be smart, she would study Greek. To be brave, she would learn to ride a horse so well that she would be able to jump fences—even high fences." By this account, Elizabeth was a remarkable child, for she learned to be an accomplished equestrienne, and "Elizabeth was put into the highest class of mathematics and languages at Johnstown Academy," graduating at age sixteen.
