Hello, I'm no longer active on Geni. I have over the period of 2008-9 input over 30,000 profiles into Geni, so feel free to request management of any of my profiles you may be interested in.

Much of the data I input here is taken (with permission) from Dan Hirschberg's wonderful Krakow website:

and especially

I also use Yad Vashem's testimony pages:
