For a friend - she is searching for Avram Stein and his sister Mattie born in the late 1950's or early 60's in Israel. Mattie's married name is not known. Their parents were Leib Stein and Toni nee Berkovitz (or Berkowicz). They once had a tool and dye shop in Tel Aviv, which was aready closed when my friend visited in 1979. They had a home in Hulon. Toni's parents (first names not known) lived on a short street south and perpendicular to Bartenura Street (which is close to Nordau St) in Tel Aviv.
