111 Introduction Have you ever wondered who your great-great-great-grandfather was, what he looked like, when he lived, and what he did? For Olena Solovey, these questions became the starting point of a profound journey into the past. While a year ago her knowledge of family history extended only to her great-grandfather, today she has constructed a detailed family tree that includes approximately 70 individuals across 11 generations of the family. (Pic.1) The earliest identified ancestor is a distant great- great-great-grandmother, Anna, born in 1710. This research demonstrates that genealogy is not merely a hobby but a systematic scientific inquiry that restores the "living fabric" of history [1]. Picture 1. Olena Solovey’s family tree Methodology and Archival Investigation While genealogy is often considered a hobby, in our case it developed into a systematic study involving elements of archival research. The goal of this work is to reconstruct lost historical connections, restore forgotten names, and identify burial locations. The research began with a specific, tragic case: the disappearance of Olena‘s great-grandfather during World War II. No official documents or burial records had been preserved in the family. The only clue was an oral account suggesting he died during a German air raid on a military crossing over the Dnipro River. By utilizing international digital archives and open-access databases, Olena analyzed military records and digitized handwritten documents.
