Among the most common last names on Yasni Staack is on position 4430.
According to opinion of my grandparents Staal, the name originates from the northern German region and has the "Staaken" of a boat (driving a boat "gestaakt" using a long wooden pole, with the bottom of the water) will do. Whether this is provable, however, is not known to me
