The occasion was the bar mitzvah of Leon Gabai who you can see
on the left of the photo in his bar mitzvah outfit! The others
in the photo (from left to right) are Leon's grandmother,
Maria Cohen Gabai, his sister Maria Nouri Gabai, and his
mother Rachel Arditti Gabai.
Leon survived the Holocaust together with his wife and
daughter by getting the last boat to Chile (as they were
Sephardim and spoke Ladino they had no trouble with Spanish).
Maria Cohen Gabai and Rachel died circa 1925. Maria Nouri
became Maria Nouri Honig (later Holton) and escaped with her
husband and son to England.
