The Grieser Family

A Journey from Germany to the American Frontier


Ignatius Grieser and Katharina Gute were part of the great wave of German immigration to America in the mid-nineteenth century. Their story is one of courage, hardship, and the pioneering spirit that helped settle the American West. From the villages of Baden and Rheinland-Pfalz in Germany to the bustling streets of St. Louis, the farmlands of Nebraska, and finally the rugged territory of Idaho, their journey reflects the immigrant experience of countless families who sought a new life in America.

Ignatius Grieser: Origins in Baden

Ignatius Grieser was born on January 30, 1835, in the town of Bühl, located in the Baden region of southwestern Germany. The very next day, January 31, he was baptized at the Catholic church in Bühl, following the customs of his devoutly Catholic family. He was the seventh of nine children born to Franz Xaver Griesser (1794-1867) and Maria Anna Weissenberger (1799-1863), who had married in 1820.

Growing up as the fourth son in a large family in 1840s and 1850s Germany, Ignatius would have witnessed the social and economic pressures that drove many Germans to seek opportunities abroad. Political unrest, economic hardship, and limited opportunities for younger sons who wouldn't inherit the family property were common reasons for emigration during this period. Of all the Griesser children, only Ignatius and his sister Anna Maria chose to make the momentous decision to leave their homeland.

Sometime in the mid-1850s, when Ignatius was likely in his late teens or early 20s, he and Anna Maria embarked on the arduous journey to America. Following a common route for German immigrants of that era, they likely sailed across the Atlantic to New Orleans, then traveled up the Mississippi River to St. Louis, Missouri—a city that was rapidly becoming a major destination for German immigrants and a gateway to the American West.

Katharina Gute: A Daughter of Rheinland-Pfalz

Katharina Gute was born on September 2, 1837, in Landstuhl, a town in the Rheinland-Pfalz (Rhineland-Palatinate) region of western Germany. She was baptized the following day, September 3, at St. Andreas Catholic Church in Landstuhl. She was the fifth of seven children born to Peter Gute (1798-1869) and Barbara Glas (born around 1800), who had married in 1824 in nearby Kindsbach.

As the third daughter in the family, Katharina grew up in a region steeped in history and affected by the same economic pressures that drove emigration throughout German-speaking lands. Like Ignatius, she would eventually make the bold decision to leave everything familiar behind. Of the Gute children, only Katharina and her brother Johann chose to immigrate to the United States, probably also in the mid-1850s.

The journey across the Atlantic for a young woman in her teens required tremendous courage. Whether she traveled with her brother Johann or joined other family connections already in America, Katharina would have faced weeks at sea in crowded conditions before arriving in the New World. Like many German immigrants, she eventually found her way to St. Louis, where a thriving German-speaking community provided a bridge between the old world and the new.

A New Life Together in St. Louis

Ignatius and Katharina's paths crossed in St. Louis, where both had settled after their separate journeys from Germany. On May 1, 1858, Ignatz Griser and Catharine Gute—as their names were recorded in American documents—were married in Saint Louis. Ignatius was 23 years old, and Katharina was 20. Their marriage united two German immigrant families and marked the beginning of their life together in their adopted homeland.

Ignatius worked as a carpenter, a skilled trade that provided steady employment in the rapidly growing city. By 1860, the young couple had welcomed their first child, Anna, born November 17, 1859. The census that year shows them living in St. Louis Ward 1, with Ignatius listed as owning $250 in personal property—a modest but respectable amount for a young craftsman. Their household was recorded as the Ignaz Briesser family, showing yet another variation in the spelling of their surname, common in an era when many census takers and clerks anglicized or phonetically spelled unfamiliar German names.

Their second child, Frank Peter, was born on September 12, 1861, in Louisiana (based on the 1870 census entry), suggesting the family may have temporarily moved outside St. Louis, perhaps for work opportunities. They soon returned to St. Louis, where by the 1870 census, Ignatius had achieved considerable success. The family, now including young Adolph (born April 20, 1869), lived in St. Louis Ward 3. Ignatius had accumulated $4,000 in real property and $400 in personal property—a substantial estate that spoke to his hard work and business acumen over the previous decade. Both Anna and Frank were attending school, showing the family's commitment to education and their children's advancement in American society.

Westward to Nebraska

After 1870, the Grieser family made another significant move, this time to Cedar County, Nebraska. This was the era of westward expansion, when the Homestead Act and the promise of cheap land drew thousands of families to the Great Plains. For a skilled carpenter like Ignatius, the growing settlements of Nebraska offered both land opportunities and the chance to apply his trade in building the infrastructure of new communities.

It was in Cedar County that the family expanded significantly. Four more children were born on the Nebraska frontier: Amelia (March 13, 1871), Katherine (May 10, 1872), Elizabeth "Lizzie" (December 13, 1874), and Charles Frank (June 13, 1876). Life in Nebraska would have been considerably different from St. Louis—more rural, more isolated, and requiring the kind of self-sufficiency that characterized pioneer life. The children would have grown up experiencing the wide-open spaces of the plains, the challenge of prairie farming, and the tight-knit community of other settlers, many of whom were also German immigrants.

The Idaho Territory

Before 1879, the Grieser family made their final move, this time to Latah County in the Idaho Territory. Their daughter Anna had married John Nicholas Brocke in 1877, and they joined the Brocke family for the journey to Idaho. The region around Genesee was being opened to farming, and the rich volcanic soil of the Palouse region promised excellent wheat-growing conditions. For a family with seven children and dreams of establishing themselves on the land, Idaho represented a new frontier with fresh opportunities.

However, this new beginning would be tragically cut short. Ignatius Grieser died before June 15, 1879, at the age of just 44, from suicide by strychnine poisoning in Genesee. The San Francisco Bulletin newspaper reported on June 15, 1879, that "Ignatius Grieser, a German, who had met reverses, living near Lewiston, Idaho, committed suicide by taking strychnine." The reference to having "met reverses" suggests he had experienced financial or personal setbacks that led to this desperate act. He was buried around June 15, 1879, at Genesee City Cemetery in Genesee, Latah County, Idaho.

Ignatius's death left Katharina a widow at age 41 with seven children ranging from 19 years down to just 3 years old. The challenges she faced must have been immense—managing a farm in a frontier territory while raising a large family alone.

Katharina's Strength and Perseverance

The 1880 census, taken just a year after Ignatius's death, shows the family still together in Township 37, Nez Perce County (which would later become part of Latah County), Idaho. Catharine Grieser was listed as the head of household, a widow engaged in farming. Frank, now 18, was at home and surely helping with the farm work. Also living at home were Adolph (11), Amelia (9), Katharine (8), Lizzie (6), and Charles (4). The older daughter, Anna, had already married John Nicholas Brocke on April 24, 1877, in Cedar, Nebraska, and her son Frank, lived nearby.

Later in 1880, Katharina married Xavier Heinrich (1851-1909, also known as Henry), who was born in 1851 in Germany and was about 14 years younger than her. This marriage provided companionship and likely assistance in managing the farm and caring for the younger children still at home. Xavier and Katharina had one child, John Martin Henry (1881-1953). They eventually moved to Chicago, Illinois, where Xavier died in 1909 at the age of 58.

After Xavier's death, Katharina returned to Latah County, Idaho, where most of her children had settled and established their own families. She spent her final years in the community she had helped to build, surrounded by her children, grandchildren, and the German immigrant community that had taken root in the Genesee area.

Katharina Heinrich died of pulmonary edema on November 16, 1920, at the age of 83 in Genesee, Latah County, Idaho. John M. Henry was the informant on her death certificate. She was buried on November 20, 1920, at Saint Mary Catholic Cemetery in Genesee, joining the Catholic community she had been part of since her baptism as an infant in Germany more than eight decades earlier. Her long life had spanned continents and witnessed the transformation of the American West from frontier territory to established communities.

The Next Generation

Ignatius and Katharina's seven children all survived to adulthood and married, establishing their own families primarily in Idaho and contributing to the settlement of the region. Their descendants numbered in the dozens by the time of Katharina's death, and the Grieser name became well-established in Latah County and the surrounding area.

  • Anna Grieser Brocke -- Born November 17, 1859, in Saint Louis, Missouri, Anna was the eldest child. She married John Nicholas Brocke on April 24, 1877, in Cedar, Nebraska, when she was just 17 years old. Together they had eight children. Anna died on March 19, 1936, in Kendrick, Latah County, Idaho, at the age of 76.
  • Frank Peter Grieser -- Born September 12, 1861, in Louisiana, Missouri, Frank was the eldest son and second child. He married Catharina Christina Spielman on June 17, 1889, in Uniontown, Whitman County, Washington. They had ten children together. Frank died on August 13, 1941, in Genesee, Latah County, Idaho, at the age of 79.
  • Adolph O. Grieser --Born April 20, 1869, in Saint Louis, Missouri, Adolph was the third child and second son. He married Theresa Henrietta Baumgartner on November 23, 1891, in Genesee, Latah County, Idaho. They also had ten children. Adolph died on March 5, 1941, in Moscow, Latah County, Idaho, at the age of 71, just five months before his brother Frank's death.
  • Amelia Grieser Wernecke -- Born March 13, 1871, in Cedar County, Nebraska, Amelia was the first child born on the frontier. She married Charles Wernecke in 1888 in Nebraska. They had five children. Amelia lived the longest of all the siblings, dying on April 1, 1953, in Genesee, Latah County, Idaho, at the age of 82.
  • Katherine Grieser Peterson -- Born May 10, 1872, in Cedar County, Nebraska, Katherine married James W. Peterson on March 28, 1895, in Grundy County, Iowa. They had six children. Katherine died on June 28, 1950, in Lewiston, Nez Perce County, Idaho, at the age of 78.
  • Elizabeth "Lizzie" Grieser Hasfurther -- Born December 13, 1874, in Cedar County, Nebraska, Lizzie married Joseph Nicolaus Hasfurther on July 18, 1893, in Genesee, Latah County, Idaho. They had five children. Lizzie died on July 25, 1939, in Genesee, Latah County, Idaho, at the age of 64.
  • Charles Frank Grieser -- Born June 13, 1876, in Cedar County, Nebraska, Charles was the youngest child. He married Anna Barbara Hasfurther (sister to Lizzie's husband Joseph) on June 22, 1898, in Genesee, Latah County, Idaho. They had ten children. Charles died in 1961 in Genesee, Latah County, Idaho, living to see the transformation of America through two world wars, the Great Depression, and into the modern era.

Historical Context

The Grieser family's journey reflects several important historical movements of the nineteenth century. Between 1820 and 1920, more than 5.5 million Germans immigrated to the United States, with the peak years occurring in the 1850s and 1880s. Many, like Ignatius and Katharina, were drawn by economic opportunity and the promise of land ownership—something often unattainable for younger children of large families in Germany.

St. Louis, where the couple settled and married, was one of the primary destinations for German immigrants in the mid-1800s. By 1860, Germans made up nearly 60% of St. Louis's foreign-born population. The city's German community created a "Little Germany" with German-language newspapers, churches, schools, and businesses that helped newcomers transition to American life while maintaining their cultural heritage.

The family's subsequent moves to Nebraska and Idaho followed the pattern of westward expansion. The Homestead Act of 1862 offered 160 acres of public land to settlers who would improve it, drawing thousands to the Great Plains. Later, Idaho Territory's rich agricultural land, particularly in the Palouse region where Genesee is located, attracted farmers seeking fertile soil for wheat cultivation.

The German Catholic community that the Griesers helped establish in Latah County remained strong for generations. St. Mary Catholic Church in Genesee, where Katharina is buried, became a center of community life for German immigrant families and their descendants. The intermarriage among German families—evidenced by Lizzie and Charles Grieser marrying siblings from the Hasfurther family—created tight kinship networks that preserved cultural traditions while building new American communities.

Legacy

The story of Ignatius and Katharina Grieser is ultimately one of resilience. They left behind everything familiar—family, language, homeland—to build a new life in America. Though Ignatius's life ended tragically, he and Katharina succeeded in establishing a family that took root in the American West. Their seven children all survived to adulthood and raised families of their own, producing dozens of grandchildren.

Katharina's strength in particular deserves recognition. Widowed at 41 with seven children, she not only kept the family together but saw all her children established in stable marriages and productive lives. She lived long enough to see her grandchildren grow up and to witness the transformation of Idaho from frontier territory to an established state (Idaho achieved statehood in 1890).

Today, the descendants of Ignatius and Katharina number in the hundreds, spread across the United States and beyond. The family name appears on gravestones throughout Latah County, testimony to the lasting impact of two young German immigrants who dared to cross an ocean in search of a better life. Their graves in Genesee—Ignatius at the City Cemetery and Katharina at Saint Mary Catholic Cemetery—mark the final resting places of the patriarch and matriarch of an American family whose roots reach back to the villages of nineteenth-century Germany but whose branches have spread far and wide across their adopted homeland.
