Rebbetzin Chana was born in 1880, on the 28th of Tevet, in Nikolayev, Ukraine, to Rabbi Meir Shlomo and Rachel Yanovsky. She was the eldest of four children: she had two sisters, Gittel and Ettel, and a younger brother, Yisrael Leib, who passed away as a youth. Rabbi Meir Shlomo was chief rabbi of Nikolayev; indeed, the Yanovskys were known as a prestigious rabbinical family of scholars and leaders.
