The questions Family Religion and Religious Background seem to parallel the questions Religious Views and Religious Denomination, but they are phrased differently. The first is my family when I was growing up, while the second is simply my family. So as it happened, I was not thinking of the same families when answering them! Perhaps I should have paid more attention the name of the question Religious Background, which I really only noticed just now when I wanted to identify it for this comment. You did not in fact get information about my religious background in my answer to that question; you got information about the religious background of my spouse of less than 2 years (and my stepchild).
