I personally do not see what the bid deal is. Unless the "Family Tree" is a part of your Inter/national tradition, it's open to change. All of this stuff is made up on the fly and can be adapted to suit the needs of the chapter and its members. It sounds like everyone in her chapter basically fits into one of four "families" and she wants a smaller family unit. In chapters that have just one little sis per member, you would have lots of small families. I can't imagine how a chapter would all be in one of four. Probably the best way to go about this would be to get other sisters to latch onto the idea of making mini-families within each family so there won't be any hurt feelings.
