Actually, we only have 8 g grandparents and then 16 gg grandparents, then it begins doubling. Unless you are a typical modern day child and have multi-parents (my mother was married 4 times; my bio father married 3 times; adopted father married 5 times) which leads to a whole grist of grandparents. And all these people know you do genealogy and want you to trace their lines, too!!
