Thanks for mentioning the SAPP tool. I had seen it before but never really tried to figure out how to use it. Between you mentioning it and it being mentioned in another thread, I decided to give it a proper try. I had fun creating a tree for all the members of our surname cluster using David Vance's version. It's interesting to see where there might possibly be new sub-branches for testers who haven't done SNP testing. I'll have to edit it and add names to make it easier for me to read.
