This seems to show that the original plan was for Leia Blech (Samuel's mother) to sail on May 10 with her son Chaim and her daughter Beile. But their names on the list of outward passengers have been crossed out (in red ink) and replaced with the names of Samuel and his two younger sisters, who (as we know from the second and third documents above) sailed on May 10. So perhaps there was a last-minute decision for Samuel, Etel, and Perl to use the tickets instead of Leia, Chaim, and Beile? -- presumably because Beile was sick (as Samuel stated to the Special Board of Inquiry when he arrived in Philadelphia). You can see that the third, fourth, and fifth passengers on the list have had their first names crossed out and replaced in red with other names:Departure Date: 10 May 1905
Port of Departure: Liverpool, England
Destination Port: Philadelphia, USA
Ship Name: Westernland
Russian city; capital of the government of Podolia. In 1900 it contained a population of 34,483, about half being Jews. [...] During the latter half of the nineteenth century many Jews emigrated from that city to the United States, especially to New York, where they organized a number of societies; among these are the Kamenetz Hebra Kaddisha and the Kamenetz-Podolsk and Kamenetz-Podolia Krankenverein.
