Genealogy / Von Straski, Polish surname? [22]

In just a brief review, I've already learned so much. One of my great-grandmothers, Helen, was born in 1861 in Danzig. Before she immigrated in 1880, she had married a "noble". Now deceased family members remembered their name as Von Straski (?) or some variation. From what I've learned, the VON and the ski are "add-ons" that denote some type of status. Can anyone help in my search to identify granny? Thanks to any and all!
