Bronislava was born at Kamień, Włodawa County, in eastern Poland as Bronislawa Odrowaz in about 1200,[2] although some sources give a birth date of 1203[3] or 1204.

[1] She was the daughter of Count Stanislaus and Countess Anna of Prandata-Odrowaz and a cousin of Saint Hyacinth of Poland.

[3] At the age of sixteen, she was introduced by Hyacinth to a religious community of the Norbertine order at Zwierzyniec, Kraków.

She subsequently worked with the sick and poor at a number of monasteries, living in a most austere way.

She was beatified by Pope Gregory XVI on 23 August 1839,[2] after being attributed for protecting Zwierzyniec from cholera in 1835.
