Anna Jann was born of noble parentage in Stans, Switzerland, in 1854. She was still a novice at Maria Rickenbach when she was sent with two professed sisters, Sister M. Scholastica Von Matt and Sister M. Benrardine Wachter, as one of the first recruits for the young American foundation. The three arrived at Conception on June 27, 1876, in the sweltering heat of summer- no doubt a real test of their vocation, after leaving the pure mountain air of Switzerland.

At her profession on May 3, 1877, Anna received the name of Sister M. Anselmina, being honored with the same patron as Mother M. Anselma and Abbot Anselm of Engelberg. She was among the first group to make perpetual vows on the Feast of St. Michael, September 29, 1884. September 29, 1884.

Sister was a refined, cultured, and well-educated person Though she had come from a comfortable home and was unused to manual labor and self-sacrifice, she willingly embraced the labors and hardships of those pioneer days. Mother M. Anselma regarded her highly as a very promising member. She was docile— as ready to work in the kitchen and bakery as to teach in the school room. Sister picked up the English language quite readily, and was a capable teacher. She had a special gift of imparting meaningful instruction to her religion class, and was well-loved by her pupils.

After a few years her health began to decline, causing much anxiety to Mother M. Anselma, who feared she might develop tuberculosis because of a persistent cough. Sister herself said she would be happy to die, but Mother M. Anselma had placed high hopes in her and hoped God would not ask such a sacrifice from the community.

In June, 1888 Sister M. Anselmina accompanied Mother M. John  to Switzerland with hopes that it would improve her health. In October 1888 she returned in better health. She taught in local schools from 1889 until 1892. Her death in 1892 was unanticipated. On March 26 she went to St. Joseph to teach at St.  Mary's Parish school. On April 9 a message was received that Sr. M. Anselmina was very sick. She had double pneumonia. The chronicler writes that in the evening another message was received:

that told us the sad news of her death.  May the dear soul rest in peace.  We have lost much in her, and we will miss her very much but she was ripe for heaven and her exemplary life will long be remembered by all who knew her.  She has labored and worked hard for this house, and brought many a sacrifice, she died as she had lived, praying— she was a soul of prayer.
