Hello
I have a decoration that belonged to him as well along with the paper work. He was my great great grandfather's brother.
I also have the original 1823 patent of nobility issued for his grand father (also named Wilhelm), his brother's original birth certificate and his actual glasses.
The family is originally from Sweden. Settled in the Banat. Wilhelm (the grandfather) and his son, also Wilhelm were both at one time in the 12th Banater Grentz regiment. The younger Wilhelm (your Wilhelm's father) ultimately rose to high rank and settle in Cracow, Poland (then in Austrian Galicia). His son Heinrich, a lawyer, married a Polish Jewish woman... I come from that line which became completely Polonized marrying into a Polish Catholic family in the next generation. This Wilhelm, Heinrich's brother on the other hand chose a military career. He died childless at a very old age in the 1950s.
I am new to the forum - can't figure out how to post images. Happy to share some of the items mentioned above.
