It is possible to have two or more instances of XY family Tree running simultaneously on your PC. That way you can compare two or more family trees to see if they share common information. It should be possible this way, to assist in proving or disproving links between two families.
You need to have only the two files open – no other windows on your PC – then use Windows to cascade them horizontally or vertically. Some PCs do this with a right-click on the Taskbar but refer to your PC instructions if it doesn’t happen easily.
