Susan, The web address below will tell you all about the "how to" and also give you some insight about why I am so excited that you may be able to contribute to the body of work already done. It will be great to learn we are cousins. You will probably note that your John is not among the names identified in the DNA testing thus far. That is alright. IF your brother's DNA test shows a match with one of the tests already done we will be a long way toward knowing which tree your branch is attached to.
