Those women with whom nikaah is permissible

Q: If I want to marry my mother's father's brother's daughter, is it allowed in Islam? What should I do?

Q: I have been married from 10+ years. I have a daughter of 8 years. It was a marriage arranged from my family. When I saw my wife after marriage, I didn't like her but I kept patience. But since then she does things which I deny or do not allow. Then she joined a job which I said don't do. Her father supported her. Then also I kept patience. She never takes care of me like whenever I say my legs are paining or my I have headache she doesn't care and do not apply oil or do not massage despite my order. But the last thing which is very much troubling me is that she has no or very little sex drive. Approximately 1 out of 3-4 times only she agrees. I never dominate. I have asked her many times to her and her family that I will marry another girl but she is not changing and not even her family is taking this seriously. From last 3-4 years I am thinking to marry another girl. I have enough property and feel that I will able to treat them equally and with justice. 1) Whats your suggestion? 2) Is the anger of my first wife and my daughter's sadness which may come in consequence of marrying another girl, right?
