I think it has a lot to do with the member labeling her step daughter as a legacy or not. What if she had been married to Susie PNM's dad for only 1 year and has only known her for 2? On the other hand, like my step dad and my mom have been married for 20 years.......if I were a guy and my dad (step dad) was in a frat, I'm sure I'd be considered a legacy since i have no contact with the bio dad. See what I mean? I don't know.........like I've said before, my chapter of ADPi generally considers all step relationships as legacies.
