There was no casualty report for a Pentelemon Farbatiuk. But there was a report for a Stepan Farbatiuk who was wounded in 1915. He was from Zastawana Bukowina. That place is located in the Ukraine today. Stepan was in Infantry regiment Nr. 24.
I looked around Zastawana on maps of the Ukraine, but I did not seen anything resembling a Gurcauti, or Cercauit.
