Both of my Grosser great -grandparents were board members of a burial group from Makhnovka but neither was from there. They and several of their children are buried in the society’s plots. The connection was that their daughter’s husband’s mother was from Makhnovka. Given how many of my relatives are in the society’s plots( but the daughter and her husband, my grandparents, are not there) I could have thought that branch of my family was from Makhnovka. They were not.
