I looked in the Swedish "statskalendern" from 1880. Statskalendern are were important people in Sweden was listed with there ODM´s. I found 4 persons who hade recived this order.
Carl Herman Oscar Ennes, Ärekors af Hohenz. Hus 0. 3:e kl.
Frih. Gustaf Johan Wilhelm Ehrenborgh, Ärekors af Hohenz. Hus O. 2:a kl.
Sven Hjalmar Thestrup, Ärekors af Hohenz. Hus-O. 3:e kl.
Olde, Emanuel Mathias, Ärekors Hohenz. Hus. 0. 3:e kl.
So these person would have gotten the order before 1880.
