From the sounds of it, none of the items you have would be helpful. They are too new. For example, my father had a really old photocopy of his grandfather's immigration pass. I could barely make anything out on it, just a village in German, Neudorf. But my researcher knew that the Czech version of that was Nova Ves, and the search was on. Likewise, on my grandmother's baptismal certificate, it had the page number, and the researcher was able to go right to the spot where the original was recorded. My father had translated everything, but missed that one item. If I hadn't made a digital image to send my researcher, it would have taken him a lot longer to find things.
Which brings up the question: who in the family has all these old documents? Or did they get cleaned out? We need old stuff that didn't originate here.
