HOLOCAUST SURVIVORS, IN U.S. REUNION, ASK WORLD TO REMEMBER
Some were searching for a brother or a sister. Others were trying to find more distant relatives or old friends. But many who came to the reunion of survivors of Nazi Germany's concentration camps were just searching. ''I'm looking for anyone - cousins, friends, anyone from my town,'' said Genia Lemel of Milwaukee, a survivor of Hasag concentration camp in Poland. ''But no one is here. No one is left. I know it, but I keep hoping.'' The woman was part of a group of 12,000 to 15,000 Holocaust survivors who gathered here today for the start of a three-day reunion of European Jews who survived Nazi brutalities, the largest of its kind ever held. Tonight, President Reagan said in a speech to the survivors, ''Our most sacred task now is insuring that this greatest of human tragedies, the Holocaust, never fades -that its lessons are not forgotten.''
