I have visited Wielkie Oczy. There is a lovely restored synagogue at the entrance to the town and a gated cemetery with a few headstone artifacts. I have many photos if you like. The village is very close to the modern border with Ukraine, but at the time of Galicia (Austro-Hungarian Empire, pre WWI), it would have not been unusual to travel to Lemburg/L'viv/Lwow given the close distance--a half day's travel by buckboard--even closer by train.
My portion of my family originated in Wielkie Oczy in the late 18th century--HOLTZ/HOLZ.
