From National Catholic Register: Wanda Boniszewska was a Polish nun, a member of the Congregation of the Sisters of the Holy Angels, who died March 2, 2003. The process for her beatification was launched by the Archdiocese of Warsaw in 2020.
What is distinctive about her? Two things. Sister Wanda was said to have had mystical visions, which she wrote down. She also was said to have borne for some period of her life (at least in the 1930s) stigmata — wounds in her hands, feet and side, and marks of scourging. They manifested themselves irregularly, but usually on Thursdays and Fridays, and particularly during Lent.
