True, you can't change the gravestone. I thought maybe the size of the gravestone was based on how much money they had, but Lifetime Happiness sounds good, too. In my 12 generation Legacy family, founders and most of their direct descendants had the largest one. The in-laws always had the smallest ones. Many of those I never controlled, but if they contributed to the family legacy they got to be in the family cemetary. Yeah, the more I think about it, the more I think it's likely determined by Lifetime Happiness.
