Puzzling Pieces

Thinking of you this first day of Autumn with a lovely card I received years ago from Aunt Hedy!

As the leaves begin to change, it's the perfect time to climb back up our family tree in search of clues to some unsolved mysteries. I did find some puzzle pieces up there, but I need your help in fitting them together:

28 April 1902
Adam Lalensky* (28) of Baba, Poland arrived in NY aboard the Ryndam. The manifest indicated he was going to his brother-in-law, F. Pieloscik (sp?), in Housatonic, MA. (*Actually Adam Zalensky on the manifest.)

17 May 1903
Joseph Grala (17) of Baba, Poland arrived in NY aboard the Arcadia. The manifest indicated he was going to his uncle, Adam Zalesky, in Pittsfield, MA.

13 April 1905
When Maryanna Grala (17) of Baba, Poland arrived in NY aboard the Rhein she was going to her brother Josef Grala in Pittsfield, MA. We've determined she was Bronislaw's sister.

20 November 1906
Dorotea Zalinska (38) of Baba, Poland arrived in NY aboard the Oldenburg. The manifest indicated she was going to her husband, Adam Zalenski, in Pittsfield, MA. [This is Dorotea Pielosick.]

19 February 1912
Branislauf Grala (20) of 86 Turner Avenue, Pittsfield, MA married Theophila Rogowska (18) in Housatonic, MA. (86 Turner Avenue was the home of none other than Adam Zalinsky!)

Based on these clues, Aunt Joan and I feel certain that Josef Grala and Adam Zalinsky are related to us in some way ... that perhaps we have more relatives waiting to be found. Afterall, Baba isn't that big a place for so many Gralas to be unrelated! But who is Adam Zalesky and how is he connected to our family history?

If anyone can help us solve this mystery, we'd appreciate hearing from you!
