Feigi, Reb. Nachman of Breslov's mother, was born in Medzeboz to her parents, R. Yechiel Ashkenazi and Adil, the Baal Shem Tov's daughter.

Feigi married R. Simcha in 1763. This match had been agreed upon by the Baal Shem Tov and R. Nachman Horodenker, Rabbi Simchas's father, before either Feiga or her husband had been born. It was the "fee" R. Nachaman Horodenker was willing to pay the Baal Shem Tov for his arranging R. Nachman's own marriage to the sister of R. Yitzchok Drovitcher.

Feiga was known for her ruach hakodesh and righteousness. She was called "Feigaleh the prophetess" by her renowned brothers R. Ephriam of Sudylkov and R. Baruch of Medzeboz who were aware of her ability to see into the future and speak of events before they actually came to be.

Feiga's name appears time and again throughout the early history of Breslov Chassidut. Yet, perhaps the greatest tribute to her valor came from the R. Nachman himself who cautioned that any one wising to have a request of heaven answered in his merit should refer to him as R. Nachman, son of Feiga (unlike others who after their passing are recalled by their father's name).
