Do we have free will or are we wholly determined by antecedent causes?

I like to think that humans have a free will to do as they chose. But, I also do believe that some things are predetermined by factors one can’t control. Who our family is, where you go to school as a kid, who you marry (pre-arranged marriage), those are the types of things that you can’t control. So the human life is a mixture of both free will and antecedent causes.
