Cecelia Kaminski married Casimir Joseph Zdrojewski; you can check out the relationships at the page Familiae Personae Zdrojewski.
Two of their three children are in this photo: Celine between her Mama and her Grandmama, and Paul seated in front giving the photographer a great baleful look. Notice the young man behind Cecelia.
Here is that young man again in the photo below, which was stuck in a book in the Upstairs Research Loft of the Coot Hill Family Historical Preservation Society.
Who is he? Who are they all? They look like a group of siblings and cousins. In fact, I wonder if those are Celine and Paul Zadner perched on top of the piano. Anyone have a clue to the identity of the others or location of the house?
Update 02/27/12: Paul Zadner helps us out here: "I am on the top of the piano but my sister is the little girl standing at the opposite end. The girl on top of the piano is already dead. I have the religious picture that sits over the piano and it is not in the best condition. This photo was at my cousin's house who is playing the piano."
