If anyone who uses the WikiTree Browser Extension wants to find holes in the trees for our notables, use this link,
https://www.wikitree.com/index.php?title=Special%3AMyConnections&w=Carey-6470
but replace the Wiki-ID with the person you're working on. Click the Missing Connections Table button for each generation to find missing family members. After the table loads, click on that button again if you want to see the simplified version and not the table.
This works whether they're connected or not!
I'll be checking out C.T. Vivian's branch to see where I can add some profiles.
