Hi, Amy-
I'm a Plack! If you give me an address or email address, I'll be glad to share the info I have. I have 2 brothers (Placks) in Kansas and Oregon. My father (a Plack) still lives in the Buffalo, NY area. Some of his generation are in Pennsylvania. I have info on a couple of previous generations. I also have a list of Placks across the country. I don't know their relation yet. My Dad met a Donald Plack from California in the navy at the end of WW2.
