I've looked through many of the matches for my DNA but am having problems. I see little coloured icons for the following things:

Orange/brown for the other persons tree
Blue for my own tree
Green for someone on both trees
Some with people inside the icon, others plain

When I enlarge the map to see all the icons I've never seen one in green that says it's on both trees. And I have 25 pages of matches! So it looks as though nobody is related to me in any of those matches, or am I just not interpreting them properly? And, could it be, that none of my relatives have so far taken a DNA test, especially as most of the people from other trees seem to be in the USA?

Thanks for any help.
