Am trying to get to this particular family tree. www.gencircles.com/globaltree

Well, the link works, but it's to the search page, not a particular family tree. What is your question?

Is Ronalds a surname you're looking for?
There are lots of sites that people have submitted their family trees to. Give a bit more detail and we'll help you find what you're looking for.
