I am trying to find my great-great-grandfather Anthony Chorosevic. (Alternate spellings: Antony, Antoni; Horosevic, Horosewic, Horosewiecz)

He emigrated from Poland to the U.S. I have tracked down his Declaration of Intention from 1917, as well as a Census reference in 1930.

The DOI shows him as having arrived in the U.S. on Dec. 26, 1906 aboard the Pretoria from Hamburg Germany. His last foreign residence is listed as "Walschav, Russia" (Not sure about the spelling)

However, I cannot find an arrival of the Pretoria for this exact date.

Compounding the problem is that the census shows him as arriving in the U.S. in 1908.

I have searched a lot of Ellis Island (gold) and ancestry.com, but so far have had no luck finding him.

Anyone have any suggestions? Anyone able to do a lookup?
