Search for Possible Ancestor

I am searching for information on Eisik Pelsy. He is listed on the passenger list of the City of Chicago which left Liverpool and Queenstown and arrived in New York on 08/22/1891. His origin is listed as from Poland, born 1871 and arrived in New York at age 20. This is the only information I can fined on Eisik Pelsy. I have been on many many geneology sites and message boards and can find nothing about him. Can anyone help. Thank you.
