I have a feeling something will come along about her children, but I don't know yet :)
She also made the point to never marry. She became Prime Minister aged 31, the third female Prime Minister in Britain in spite of its long history, and she did her job well.
She couldn't keep everyone happy, no one could, but she kept an awful lot of them happy and appeased the ones that she couldn't as best she could. Politics was a difficult game for anyone.
She was good at this job, arguably better than anyone had seen in a long time.
And she did it alone. She didn't rely on a husband or a partner, and made it very clear that she was not interested in dating. It wasn't that she was keeping herself unhappy just to spite her father - she just never met anyone she was honestly interested in. Her father had left her with a rather poor impression of men and the feminism at St Trinian's had just broadened her horizons.
She did adopt though. By the time she was forty, she had five children, from all over the world, giving each of them a better life.
Catherine raised them alone.
And all five of her daughters did something wonderful with their lives.
She made sure to post every newspaper article about them to her father.
