I was quite surprised to see that someone was actually searching the Family Roth from Berken. Berken is now just a hotel/restaurant and a couple of farms - we visited there in 2008 - my family is originally from Berken, it was their branch's "heimatort" or place of official registration.
I would LOVE to see any of the records that you have if you made any copies. I have a few from a trip to Salt Lake, but found them on the last few hours of my trip so couldn't make many copies.
This is the first time I've seen anyone looking at this family! My GGG Grandparents were from the area - left from Kirchberg in 1856 and settled on the border between Illinois and Wisconsin, going back and forth between Rock Co, WI and Winnebago Co, IL. Other surnames in that area connected to the Roth family are: Meyer, Jordi, Iseli, Saegesser.
Hope to hear from you!
