Hello Gary,
Do not have "your" Johs in my list.
My direct line First Found Ancestor is Johann Andreas Joh, father of Johann Baltasar Joh who was born in 1704.
Check
http://www.prodigyweb.net.mx/mroek/personal/139 Johs! And still a lot missing ;-)
I just came 5 years ago from Germany to Mexico.
My Grandma was a JOH!
BTW: I guess the "Ulrich" surname should be Urich/Urig.... there were a lot around in that area!
