I was checking the message boards for a similar issue and found your thread. I dont have any EXACT info on your Ulrich Amsler, but he must be a brother of who I'm trying to find info on. "Heinrich Amsler" is my ancestor and he also married a Fasler. He is from Densburen and was born in 1795...weird. I feel like we're close to something, I will share what I find with you if i learn more, so far I am up against a dead end trying to go any further on his line. I have family that still live there in Baden and Densburen, do you?
