So, in the relationship selections there are "parent of" and "child of" as well as "Offspring off" and "Immediate Ancestor of" options. Why did we need both? What am I missing? I know that if I want to see a family tree in relationship view I must use the offspring and ancestor option, but I'm not sure why parent/child is not sufficient for this? Is there a reason to use both? Right now I have four relationships in my contents pane (child of x2 for each parent and offspring of x2 for each parent) and that seems like a strange way to set it up.
