I can't figure out the meaning of 内外 and the nuance of 親族 because of it in the following passage. I think I'm more or less understand the basic concept of 内 and 外. I also looked through the dictionary and it is written that 内外 could mean incide the country and outside. But could the author be talking about the people from family and outsiders in this context with it? One line after it, the author uses the word 親族, that's where I lost it. So is he talking about the other family members, who are the enemies of the stepfather? Or means the situation itself, where his sole daughter has to inherit everything?
Fast translation: Being known for his shrewdness, stepfather made lots of enemies (incide the country and outside/from his family and outsiders)
