Kama,
I have these pictures from second husband of my grandmother;
Piotr Gąsior named "Piecia" is on left side of this picture
http://hannak-familie.eu/hohnstein/pages/image/imagepage20.h...and on many other (distinctive hairstyle) :)
I am very glad that I could share it :)
It will be nice, if you find some additional informations in diaries.
If you want, I can try to scan them in better resolution and send you.
Best regards
Witold from Wrocław
