Rachela Radzyner was born in 1887 and lived at the same addresses as Rebeka Radzyner. Therefore, I concluded that Rachela was Rebeka's mother. In addition, I also found several other Radzyners that were most likely siblings or at least family members of Rebeka's, who lived in all the same locations as hers:
Ajdla Radzyner (F): died Sept 16, 1942: DOB: October 26, 1912
Chaim Radzyner (M): DOB: September 6, 1908
Elka Radzyner (F): DOB: February 18, 1910
