I looked for a voyage dated 1906.
Arrived: New York 6 Feb 1906
Jacob Domenick Aged 34 Polish
Marlin Domenick Aged 19
They are bracketed together and it says what looks like "Cousins". They are going to Chicago. Difficult to make out the address they are going to. It looks like Jusef and his surname is impossible to read, but there is something like "lile" or "lich" at the end of the surname. The address is 48th Street 132(?) Chicago.
I am not sure about the person Jacob was with. It looks like Marlin.
There is a Census for 1910, but I am not sure if it is Jacob, because the date doesn't fit in with the date on the above ship, and neither does the date he arrived in USA.....
Name: Jacob Dominich
Address: Boyne Ward 4, Charlevoix, Michigan.
I noticed a Judes Becker, also on the "Blucher" but arriving New York a year later on 23 Jan 1907. He (or she) was aged 16 Born 1891 Eprisek. Judes was going to: Father, Aron Becker 125 Madison St, New York. Hebrew.
