Chana Schneerson's great grandfather was Abraham David Lavut, a composer of Jewish literature upon which Chabadic prayer books are based (including the Siddur Im Dach).
[1] She was the eldest of four children, having two sisters, Gittel and Ettel, and a younger brother, Yisrael Leib, who died in his youth.
[2] As a teenager, she was educated by her father,[1] and when a maamar would arrive from Lubavitch, she would meticulously and faithfully transcribe it, making it available for other Chasidim.
In 1900, she married Levi Yitzchak, a great-great-grandson of the third Rebbe of Lubavitch, Rabbi Menachem Mendel Schneersohn, also known as the Tzemach Tzedek.
She transported Levi Yitzchak's religious writings, considered illegal contraband under the communist soviet regime, focused around the Kabbalah, upon moving.
