Can you help identify the people in these paintings?

In 1939, the German forces thundered eastward across Poland in a Blitzkrieg (Lightning War), laying waste to everything in their path.  One of the buildings which was ravaged was the home of my grandparents, Antoni and Zofia Werner Dunin, at that time a young married couple living at Bogusławice, near Poznan.  They were both killed during the events of September 1939, though their three children (all under the age of 6) managed to survive through the assistance of other friends and relatives.

Much of my family's heritage was lost, but a few items have been recovered, and cherished within my family to this day.  Alas, the identification of the people in these paintings was lost with the chaos of the war.

I, and other members of our surviving family, would very much like to learn the names of the people in these paintings, so that we can pass this information about our mutual ancestors down to future generations. If you can help identify any details on these paintings, please let me know!  Even small bits of information may be helpful.

Thank you,
