HI, yes as I mentioned above they are still Guests. After sending a personal message I was able to get the information I needed from Lindner-73 and could reject the match,
I sent both of them personal messages with the info on my part of the tree to see if they could say if it was the same person or not. I only did the trusted list thing since the unresponsive form asks for it. And I would agree they would probably not want me on their trusted list. I added my info/data of my profil in the text so that they would know if they are the same.
I sent David a personal message, with the data from my profile, hopefully he'll respond,
