I suspect the vessel you are looking for is actually the SS Wittekind, which arrived in Baltimore on 26 May 1910. The passenger list is available on Familysearch, and Marcin Glowacki, aged 18, is listed among the passengers (2nd on the list).
As an interesting aside, the SS Wittekind was seized by the United States in 1917, eventually becoming the cargo ...
I can contribute three names to the passenger list that you seek.
My grandmother Margaret Malcolm was traveling with my father Douglas Malcolm and infant uncle George on the Galway Castle when it was torpedoed. Margaret and Douglas survived but George did not and is buried in, I believe Plymouth.
