Sora (Latvian: Zara Berelson; pre-reform Russian: Сора Мовша-Берковна Берелсонъ) was born on July 23, 1909 (Julian calendar date) in Riga, Livonia governorate, Russian Empire.
Later in life she likely converted her birthdate to Grigorian calendar, and therefore used the date of August 5, 1909.
She might have still been alive in 1978 because there's a note dated July 19, 1978 beside her original record of birth.
