I understand, I think, as to why each person (living) needs to create their own account (privacy). HOWEVER, I believe this also sets up a situation where there are duplicate ID's for the same person and thus the painstaking measure of having to "merge" them after they pass. Why in setting up a new account, the person just can't enter their PID already? I would think it would be better for the trees to be "merged" so that the tree can grow. If other persons are able to "add" to my tree, why can't my husband, children, and extended family be all part of the "larger" merged tree?
