I have come across this photo from Pankiewicz.net, where it is listed as follows:
‘Janina Koczoń z domu Pankiewicz – córka Franciszka Jana Pankiewicza (syna Bartłomieja Jakuba), zginął podczas I wojny światowej – wraz z mężem Janem Józefem ( górnym rzędzie). U dołu w berecie córka Barbara Koczoń’
Rough English Translation:
“Janina Koczoń of the house Pankiewicz – daughter of Francis John Pankiewicz (son of James Bartholomew), was killed in World War I – along with her husband John Joseph (top row). At the bottom of the beret daughter Barbara Koczoń”
