Sometimes people ask how their Y-DNA can be matched to someone who is deceased if there is no Y-DNA from the deceased person for comparison purposes. The method is called triangulation and it works like this. You identify and test two living men who each claim descent from a certain paternal ancestor through two different sons of that paternal ancestor and compare their Y-DNA. If it matches and there is a good paper trail, you can be fairly certain they both descend from that paternal ancestor. The more men you can find and test who descend from different sons of that ancestor, the better.
