Extend permissions to living people
I'm working on my family tree and I add my siblings and their families. After that, my older brother open his own account, find 'my' tree and added his name and those of his family. So, I think, there is at least two records for my brother. If my nephew open his own account, it'll be two (or more) records. Yes, some of the newest members of my family are very young or there is no yet sources over them. Yes, some cousins lives in other countries... their parents emigrate and their families lost connection with us. They are 'creating' new trees.
Of course, I would like the family to find as much information as possible without having to create a new tree and get to know the rest of the family, including those who are alive. They are the ones who will be able to resume family contact and build new ties.
Can you think a way to facilitate this?
