For Krüsmann there are 9 on Yasni with different names.
Among the most common last names on Yasni Krüsmann is on position 4518.
The name derives from the name meant Kreuzbauer Cruismann and whether it is a farming family farm (Cruismannhof today in Bochum) is a cross or manufacturer, I do not know (the 16th century ones). The name was changed to the 19th century simply Krüsmann.
