Help in Identifying this Uniform
My ancestors are mainly in Minnesota, Illinois, Iowa and South Dakota. The came primarily from France, Luxembourg, and Germany.
We found this photo (not sure if it is my great-grandfather, Nicholas Bertamus (or Nicolas Bertemes in Luxembourg), and we cannot identfiy the uniform.
If anyone can assist in identifying this uniform, I thank you in advance.
I have posted to Luxembourg and Germany groups, but no luck.
