Keep in mind that Lorraine and Alsace are two large areas with many small villages. Do you have any more specific names of where he may have lived?
You could also check a site called Geneanet.org. I knew one town name of my family and thru this site was able to match the matriarch and patriarch. Then the fun began!
I don't remember any Witz/Utter family but I will look thru my pictures again.
Email again to firstname.lastname@example.org
if you find more.
