Every year since 1965, survivors of the Holocaust and their families have gathered at Benjamin Hirsch’s somber Memorial to the Six Million in Greenwood Cemetery to observe Yom HaShoah, the day of remembering those who died in the Holocaust.As is customary, Ambassador Vornai Shorer, the Israeli consul general in Atlanta, attended this year’s observance, seated on the front row near Gov. Brian Kemp and his wife, Marty, which isn’t customary at all.
