Adam STROUSE and Anthony STROUSE brothers from Lithuania ship records?

I am looking for maybe 9 STROUSES who all came to the US in 1900. They are the families of two STROUSE brothers from Lithuania or Russia. I'm ultimately trying to find 1) the ship records, 2) what town they were from, 3) their parents names, and 4) any naturalization records.

I have been searching for these people for 14 years, since I was 12! I have tried name variations and sounds-like names and anything I could think of. The brother Adam and his family are my direct line. It seems maybe they all traveled together since they all came in 1900, but I don't know that for sure. I ASSUME the individual families at least came together, but even that I don't know. They all lived in Helvetia, PA and Dubois, PA.
