I made my family tree (up to great grandparents) back in 2012. I have since gotten married and added all of my husband's extended family. If I want to share his half of the tree with his relatives, is there a way to only export part of a tree? I know I can save his half as a pdf, but I'd like to share as a link so they can add their details. There's no need for them to be able to see/edit my portion of the tree though.
