I seem to see that same trend. It is pretty interesting!! I am trying to fill in the middle. I have gotten pretty far. Just got stuck at Carlisle. Started going back with Pierre Tillou who arrived America, but could not contact with Carlisle. I will find the path one day I am sure. I also see that there is a Tillou France. I thought was interesting. Thank you for your input. I have not found the Pierre Joseph Tilyou and Mary Carlisle link. I will have to keep going. Again, Thank you very much!!
