I'm giving her the benefit of the doubt, yes; but because she married him AFTER the war & there is no evidence that she met him at the camp, (you can't rely on Wiki which says "probably") It seems that he was definitely a member of the SS, but of which type I don't know.
The two main constituent groups were the Allgemeine SS (General SS) and Waffen-SS (Armed SS). The Allgemeine SS was responsible for enforcing the racial policy of Nazi Germany and general policing, whereas the Waffen-SS consisted of the combat units of the SS, with a sworn allegiance to Hitler.
He was one the lowest ranking non-commissioned officers & if he was in the combat units, it doesn't mean he is culpable of what went on in the camps which is implied in the OP article.
