My grandparents had typical names

My paternal grandparents were named Demyan and Katya, and my maternal grandparents were/are named Maksym and Peysikha. Of all only my grandmother Peysikha is alive, and she lives in a small town outside Jerusalem in Israel 🇮🇱

I am kind of detached from my past now since my parents were killed in 2022 and my brother died last year. I have to hope that the details I might want are available from my Jewish grandmother as otherwise I will need to consult with the local authorities at home in western Ukraine. I have my parents home there as my home now, since I am heir to all after my brother’s death in the war.
