[2] The young widow remarried in February 1787[2] to Dov (Berek) Sonnenberg[6] (1764–1822)[7] son of Shmuel Zbitkower.

[6] While Berek engaged in general Jewish philanthropy, his wife Temerl directed the couple's efforts to support the Hasidic movement in Poland.

[13] The couple was honored by the Hasidic leaders of their day with their attendance at their children's weddings;[14][15] they also married their only daughter to a grandson of Shmelke of Nikolsburg.

In 1810 she had purchased a home in a street "technically forbidden to Jews", and was granted an exemption from the ghetto residence laws.

[18] In 1827 she received permission from the Russian tsar to buy the estate of Jerzy de Hesse-Darmstadt, making her only the third Jew in Poland permitted to own property beyond the ghetto walls.

[17] She used her standing to influence the authorities to favor the Hasidim during the "anti-Hasidic investigations" of 1824 that were promulgated by members of the Haskalah (Jewish Enlightenment).

[20] In one instance, she helped rescind an official order barring Hasidim from visiting the tzadikim by personally appealing to the governor of Warsaw.
