Bolesława Maria Lament was a Polish religious sister and the founder of the Missionary Sisters of the Holy Family. Lament worked as a seamstress and soon joined a religious congregation 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 – Honorat Koźmiński encouraged this return – and she later founded a congregation that soon spread and took her to Russia though its revolution forced her departure during World War I. Pope John Paul II beatified Lament while in Poland in 1991.
