Blessed Boleslawa Maria Lament (3 July 1862 – 29 January 1946) was a Polish Roman Catholic professed religious and the founder of the Missionary Sisters of the Holy Family.
Lament worked as a seamstress and soon joined a religious order though left just prior to her profession upon experiencing vocational doubts; she returned to her life as a seamstress and worked with two of her sisters to support their siblings and widowed mother.
The death of her seminarian brother prompted her to return to the religious life - the Blessed Honorat Kozminski encouraged this return - and she later founded an order that soon spread and took her to Russia though its revolution forced her departure during World War I.Lament's beatification opened under Pope Paul VI on 5 April 1975 (she was titled as a Servant of God) and Pope John Paul II later confirmed her heroic virtue and named her as Venerable in 1991; the same pope beatified Lament while in Poland in 1991.
