A map will show that Krain included the area where your family was from.So I would not dismiss the manifest for Jakob SORC.Wonder why the age is written differently than the others, slants to the left vs the right as with others and is lighter.
SOREC, based on Slovenian phone book listings, would sound like soretzWhile SOREC may be of Austrian (German) origins keep in mind that Jakob declared himself to be of Slovenian Race (what we call ethnicity today) and that in the days of Austrian rule of Slovenia it would have been advantage to be Austrian vs Slovenian.This info would have been based on his Austro-Hungarian passport that he recieved before he left Slovenia.
Also the port of NY was not the only port of arrival, perhaps 25% arrived at other ports on the east coast inc. Boston, Baltimore (where many Crotians arrivied), Philadelphia and Canadian Ports.Other ports of interest may be Galveston TX and San Francisco CA.
You may be interested in the Federation of East European Family History Societies (based in Salt Lake City) which has letters written by a Rev. Trunk regarding Slovenian settlements in the US in 1912.Seems the Slovenes at Sunnyside belonged to the parish at Salt Lake City
