I am just starting to do some research for a friend on the Dluskowski name. Because the name seems to be mispelled for this family in all census records until 1930, I have not gotten too far. Since your post is five years old I will just ask if you now have more information on your Dluszkowski.
I hope to get lucky in the cenuses so as to be able to share information that I have found. Do you know if the name Dluszkowski is common or uncommon and what it means?
