Re: Lost relatives in New York #usa
I have a twofold suggestion:
I looked up Kreine's arrival in 1907. It is the old manifest style, so there is no "old country" name/address. But, it does say she was going to her brother, Wolf Berkowsky, c/o Mr Salamon, at 82 East Broadway, in Manhattan. This sounds like it might be what you call, "Our known Kreine and Wolf".
For anyone else that want a look, the 1907 ship manifest is here: https://www.familysearch.org/ark:/61903/1:1:JXXW-LY3
BTW, using sounds like on Stephen Morse's website, there is another arrival you might want to look at:
Burkowska, Karianna arriving in 1903, age 17, from Viczing. (SHIP NAME Rotterdam, ARRIVAL DATE February 14th, 1903, PORT OF DEPARTURE Rotterdam, Holland, line 9 of frame 288)
