I'm sorry, my answer may be a little unclear. According to my knowledge, in ancient novels, the fate of a character often changes greatly, especially after experiencing some twists and turns. So I guess your question is about the changes in your uncle's life, which led to the changes in your relationship with your parents. As far as I know, in ancient novels, there are often various situations in the life of the uncle's family. For example, the personality and behavior of the uncle or aunt will affect the fate of the character. Later on, his uncle or aunt might change, or his relationship with his parents might also change. The specific situation still needed to be judged according to the plot of the novel.
When I was five years old, my mother and I went to my uncle's house in the countryside for a holiday. I still remember that it was a beautiful morning, the sun had just risen, the sky was blue and the air was fresh. We took my uncle's foxtail car and arrived at this small village in the mountains.
Uncle's father could be addressed as his biological grandfather or grandmother, or he could directly address them as grandfather or grandmother. However, in some areas, people would address the man according to his seniority. The father of the uncle would be called grandaunt. In general, one could decide how to address his uncle's father according to personal habits and regional customs.
Father's uncle-in-law could be called uncle.
An uncle-in-law refers to your father's brother-in-law or brother-in-law. So if your uncle-in-law is your father, then he is your father's brother or younger brother.
The uncle that the son called his father could be called "auntie."
Father's uncle should be called 'great-uncle'.
Father's uncle could be called son-in-law.
