Mariana Allsopp González-Manrique was born on November 24, 1854, Tepic, capital of the State of Nayarit, Mexico. Her father was an English diplomat, and her mother was a Spaniard.
In 1862, when she was eight-years old, Mariana’s mother died. A nanny cared for Mariana and her four siblings until 1864 when her father sent the children to Spain to be cared for by their mother’s family.
Because of the family’s connections and wealth, Mariana had an excellent education in Spain and was introduced to the the lifestyles of the wealthy of society. Mariana, however, was not attracted to the material riches that she could have had. Rather, she more focused on spirituality and putting that into practice by serving those in need.
In 1882, Mariana met a priest in Madrid named Francisco de Asís Méndez Casariego (now a Venerable), and this meeting would help Mariana put her desire to help others into concrete actions. Father Méndez dreamt of founding a religious community to help prostitutes leave that life behind them. When Mariana heard of the priest’s dream, she felt this was what God was calling her to do with her life.
After some planning together, Mariana and Father Francisco de Asís founded a religious community of sisters on February 2,1885 called the Sisters of the Holy Trinity. The Bishop of Madrid approved the statues of the congregation in 1888. Mariana took the name Sister Mariana of the Holy Trinity in religious life.
The Sisters began in a house on the outskirts of Madrid, welcoming women who wanted to leave prostitution for a new way of life. In the house, the Sisters provided their guests with opportunities to do ironing, sewing, and embroidery. The ministry became so popular, though, that the neighbors began to complain about having known prostitutes in their neighborhood. In time, the group bought more and more houses.
Sister Mariana, along with 73 other Trinitarian Sisters, made their perpetual profesión. From that time on, the order expanded to Mexico and Argentina. As their leader, Mariana became known as Mother Mariana.
Mother Mariana died in Madrid on March 15, 1933. She is laid to rest next to the co-founder of the order, Venerable Francisco de Asís Méndez Casariego. On May 21, 2022, Pope Francis the title of Venerable for Mariana.
