What are there personality traits of the characters in Grapes of Wrath?

Tom is the main character and is the center of it all. His violent side gets the best of him when he is in the spur of the moment. He has no shame for his actions and he is very direct. He is also a very strong man. Ma is a very intelligent, strong, and guiding woman. Rose of Sharon although very whiny, comes to be a strong, independent woman that ends up nurturing a man back to life. Pa is very easy going and doesn't disagree or dare go against ma, a pretty laid back type of guy. Very relaxed and helpful whenever he can be. Uncle John thinks of himself as a sinner. He is a very depressed man that still continues to be moved and brought down by the death of his wife because he feels that it's was his fault that he did her critical medical situation wrong when she was still alive. Grandpa, when he was still alive, was a very stubborn man. He liked for things to go the way he liked and refused to think anything different. Connie just tagged along. Al seemed like a pretty strong character- a ladies man if you will. He goes around and refuses to do anything he might not like- a bit like grandpa of you combine and compare the character traits they both posses. Casy is a man that although felt bad for the wrongdoings that he committed as a preacher, he doesn't not believe in sin. He is a strong man that simply goes with the flow. He stopped trying to fight his instincts and now just goes along with it. That should be all- well just the major characters at least :)
