SS Andrew-Thomas School

SS Andrew-Thomas School Keeping past, present and future alumni, parents, family and friends informed. Our parish history begins in 1836 when Father Samuel Mazzuchelli, O.P. St.

came to Potosi and united area Catholics to form St. Thomas Parish. He built a log cabin church where the St. Thomas parking lot now lies. Our first pastor was appointed by Bishop Matthias Loras of Dubuque, Iowa. Father James Causse became the first pastor in 1840. Father Causse built the first school building in 1843. Our tradition of Catholic education has continued in our community ever since.

Tragedy struck in 1849 when cholera wiped out a quarter of the population of Potosi. Most of the remaining miners left to seek their fortunes in gold in California. Thomas soon became a small mission parish of Dutch Hollow (now Tennyson). German speaking immigrants established their parish in the mid-1840's, in what is now known as Tennyson. Father Andrew Tusch was the founding pastor of St. Andrew in 1846. In 1847, the first St. Andrew School was built. Father Nicholas Thill was pastor during the construction of the present St. Andrew Church during the years of 1874 - 1877. In 1921, Father Joseph Scheffer founded St. Andrew High School, an institution which lasted 40 years. Thomas and St. Andrew continued as separate and distinct parishes into the middle of the 20th century. In 1946, the parishes became part of the newly created Diocese of Madison. In 1964, the parishes jointly built the new SS. Andrew-Thomas School on Highway 61. In 1971, the two parishes were combined into SS. Andrew-Thomas Parish with a single pastor and a single system of parish administration and accounting. Father Richard Leffler is the current pastor of SS. Andrew-Thomas Parish.

Father was the true Shepherd of our community. He was a beautiful reflection of God’s love and he touched countless lives with his unwavering faith, kindness, and love. He shined his light on our catholic school and St Thomas and St Andrew churches. We will always remember his quote.

"Remember, God loves you more than you will ever know or imagine.” ♥️

Some history to share about our beloved SS Andrew-Thomas Catholic School. So much love and dedication. ♥️✝️

This is an enhanced postcard image depicting St. Andrew Catholic School in Tennyson, WI. The school dates back to 1847, just a year after Father Andrew Tusch founded the parish of St. Andrew Catholic Church. After serving as a grade school for 75 years, the idea of a Catholic high school originated with Father Joseph Scheffer, the pastor at St. Andrew Church at that time. The Catholic Herald website states the high school began in September, 1922, enrolling 17 students, with Father Scheffer and Sr. M. Hortense of Holy Family Convent as the teachers. Two additional nuns joined the staff in 1924, when the recorded enrollment included 3 seniors, 3 juniors, 6 sophomores, and 12 freshmen. The first high school graduation was in June, 1925, with the last high school graduation in May, 1962, after which the high school closed. On a personal note, that’s the school my mother attended, except for a couple years at British Hollow School. I also attended St. Andrew School as a 3rd grader in the fall of 1964, then we relocated to the new SS Andrew-Thomas school, which opened for students on Monday, January 4th, 1965. If memory serves, my 3rd grade classroom at St. Andrew’s was on the 2nd floor by the gym, taught by Mrs. Haverland. Razed shortly after the move to the new school, St. Andrew Catholic School certainly served the parishes and communities very well for many, many years. Submitted by Dennis & Kathy Schumacher

NEWS FLASH! On Monday afternoon, we were told that a relic of St. Dymphna, patron of those with mental illness, will be in our pastorate this weekend! The relic will be at the following churches on Saturday: St. Clement at 5 PM, and St. Mary, Help of Christians at 8 PM. On Sunday her relic will be at St. John the Evangelist at 8 AM, and St. Andrew at 10:00 AM. There will be time for prayer and veneration following the Masses. Please spread the word! We wish the relic could be at every church at every Mass, but that’s impossible. St. Dymphna, pray for us.

May Crowing brought so much love to our Catholic school.

Sunday, we celebrated a beautiful milestone as our young parishioners received their First Holy Communion. What a joy to witness their faith, excitement, and reverence as they
welcomed Jesus in a special way for the very first time.

Congratulations to each of these amazing children and to their families who guide them in faith every day. Your parish family is so proud of you! May this day be filled with grace, joy, and many blessings as you continue your faith journey.

"This is a reminder that no clergy of St. Joseph the Worker Pastorate will email you or text you and ask you for money or gift cards. Messages of these kinds are scams. Unfortunately, there is nothing we can do to prevent them. The most important thing we can do is to spread the word that these messages are scams and that we should not respond to them. Thanks, Fr. Steve"
