Wow! Lyszczyszyn in France! That's a travel.
The only information I have so far is the village my great grandmother came from. It is called Pohirtsi (Pogirci) and is in today's Ukraine. It is in the L'viv Oblast within the Sambir Raion.
Other than that, I do not know much at all. I am trying to make contact with the village and see if there are any living relatives.
