Hello, my name is Dan Fitzgerald. Much of my ancestry is Irish and British and I have a lot of information on these. I am here to look into my great-grandmother's surname Thiessen. I don't know much about German heritage, and would very much appreciate any general information on the surname. For example, does it have an occupational meaning, like "Farmer" or "Carpenter", or is it related to a place-name or any region in Germany? I speak no German and have consulted a basic German-English dictionary to no avail. Also, are Thiessens of any particular religious group or known in German and German-American history. Anyway, I am proud to have the name in my family, but I would just like to learn more about it. Thanks in advance for any help that you can provide!
