A Family History

Overview

Frederick Schaffner's life spanned one of the most transformative eras in American history. Born in the German city of Darmstadt during a period of significant political upheaval in Europe, he made his way to the New World and ultimately settled in San Francisco — a young, booming city on the edge of the American frontier. His journey took him from the cultural heartland of Hesse-Darmstadt to the streets of New York and eventually to California, where he lived out his days as a saloon proprietor, a Mason, and the patriarch of a large blended family.

Frederick married three times and raised six children across those unions, weathering personal losses and the challenges of building a life in a rapidly growing city. His story is one of resilience, reinvention, and family — a true immigrant success story rooted in the spirit of mid-nineteenth-century America.

Early Life in Germany

Frederick Schaffner was born on 16 June 1828 in Darmstadt, the capital city of the Grand Duchy of Hesse-Darmstadt (present-day Germany). Darmstadt in the 1820s was a cultured, mid-sized city — a seat of ducal power and home to a lively intellectual and artistic scene. The year of Frederick's birth also saw the beginnings of widespread economic hardship across the German states, hardship that would drive millions of Germans to seek new lives in America throughout the 1830s–1850s.

Nothing is known of Frederick's parents or siblings. Like many immigrants of his generation, the details of his earliest years were not recorded in surviving documents, and whatever family he left behind in Germany remains undiscovered. What we know is that by around 1850, Frederick had made his way to the United States — most likely arriving in New York, the primary port of entry for German immigrants of that era.

First Marriage: Susanna Hoffman

Frederick Schaffner married Susanna Hoffman around 1850, most likely in New York. Susanna was probably also a German immigrant, born around 1830, though her exact origins and parentage remain unknown. The couple settled in New York City — the teeming hub of immigrant life where German communities, known as Kleindeutschland (Little Germany), were thriving on the Lower East Side.

Their time together was brief but left a lasting mark on the family line. They had one known child:

• Herman Schaffner, born November 1851 in New York, New York. Married Mary Ann Paul by 1876, three children. Died 8 December 1921, San Francisco, California.

Susanna Hoffman Schaffner likely died before 1855, perhaps in New York. She was probably in her mid-twenties when she passed — a common tragedy in an era of high mortality from infectious disease, difficult childbirth, and limited medical care. Her death left Frederick a widower with a young son to raise.

Second Marriage: Martha Matilda

Frederick remarried around 1855, this time to a woman known to us only as Martha Matilda (maiden name unknown). She was born 17 June 1837 in Ireland — a detail that places her birth during the early years leading up to the Great Famine, which devastated Ireland between 1845 and 1852 and drove millions of Irish emigrants to America's shores. Martha Matilda was almost certainly among the countless Irish immigrants who found themselves in New York during that period.

By 1856, the family had made a bold move westward, probably by ship from New York City to the Isthmus of Panama, across Panama to the Pacific Ocean, and then by ship from Panama to San Francisco. Frederick was naturalized as a United States citizen on 1 November 1856 in the 4th District Court of San Francisco — a significant milestone. San Francisco in the mid-1850s was still riding the wave of the Gold Rush era, a chaotic, exciting, and rapidly growing city. Frederick listed his occupation as "cook," and he was described as being about 40 years old in 1867 and born in Hesse-Darmstadt.

By 1866, he had established himself sufficiently to appear on the Register of Voters for San Francisco, residing at 1 Church Street in Ward 2. He and Martha Matilda would go on to have five children together, all born in San Francisco:

• Matilda Schaffner, born October 1857, San Francisco, California. Married Lewellyn Augustus Bradford about 1876; two children. Died 24 June 1928, Alameda, California.
• Frederick N. Schaffner, born August 1862, San Francisco, California. Married Margaret Ann Ryan before 1889; three children. Died 5 April 1907, San Francisco, California.
• Louis Schaffner, born about 1864, San Francisco, California. Died after 1880.
• Charles Edwin Schaffner, born March 1867, San Francisco, California. Married Louise A. Webber before 1891, probably in Oregon; three children. Died 4 September 1916, Portland, Oregon.
• Nellie Schaffner, born 31 March 1870, San Francisco, California. Married Norman Richardson Arter, May 1888, San Francisco; three children. Died 18 November 1933, San Francisco, California.

The 1870 United States Census captures the family at a moment of domestic stability. Their household included Frederick (listed as age 45, born Canada — a curious discrepancy, perhaps reflecting a census error or misunderstanding), Martha Matilda (age 35, born Ireland), and all the children, ranging from young Herman (age 18, Frederick's son from his first marriage) down to baby Nellie (age 1). The family resided in San Francisco's Ward 2.

Tragedy struck on 23 January 1875, when Martha Matilda died in Oakland at the age of 37. The obituary published in the Oakland Tribune that same day noted she was a "native of Ireland" and invited friends to attend her funeral the following Sunday at the corner of Franklin and Ninth Streets. She left behind five children, the youngest — Nellie — just four years old.

Third Marriage: Dora Mossmann

Just over a year after Martha Matilda's death, Frederick married for the third and final time. On 20 April 1876 in Alameda, California, he wed twice-widowed Dora Mossmann, a fellow German immigrant who had been born on 20 September 1838 in Oldenburg, Niedersachsen, in what was then the Kingdom of Prussia. Dora — whose name appears variously as "Dorothea" and "Dora" in historical records — was ten years Frederick's junior, and the two would share their lives for the remaining twenty-three years of Frederick's life.

Frederick and Dora had no children together, but Dora stepped into the role of stepmother to Frederick's children and appears alongside them in the 1880 census. By then, the family had settled at 315 Lombard Street in San Francisco. That census paints a vivid picture of the household: Frederick, now 52, was working as a saloon proprietor — a respected and common occupation in the saloon-rich culture of Victorian San Francisco. Living with them were four of his children: Frederick (19, working as a bookbinder), Louis (16, a printer), Charles (13, at school), and Nellie (11, at school).

The saloon business was a fixture of working-class San Francisco life in the 1870s and 1880s. Saloons served not just as drinking establishments but as social clubs, political meeting points, and news exchanges for immigrant communities. Frederick's work as a saloon keeper placed him at the center of neighborhood social life.

Later Years and Death

By the time of his death, Frederick had moved to 423 Lombard Street in San Francisco. He died on 29 June 1899, having lived 71 years and 13 days. His obituary, published on page 10 of the San Francisco Chronicle on 1 July 1899, described him as the "beloved husband of Dorothea Schaffner" and "father of Herman, Frederick and Charles Edwin Schaffner, Mrs. Matilda Bradford and Mrs. Nellie Arter, a native of Germany, aged 71 years and 13 days."

The obituary also reveals that Frederick was a member of King Solomon Lodge, No. 260, Free and Accepted Masons. The Masonic fraternity was an important institution in nineteenth-century San Francisco — a source of fellowship, mutual aid, and community standing. His Masonic brethren held services for him at Franklin Hall on Fillmore Street between Bush and Sutter Streets.

Frederick was buried at Greenlawn Memorial Park in Colma, San Mateo County — the cemetery town south of San Francisco where many of the city's residents came to rest, as San Francisco itself had limited burial space.

Dora (Mossmann) Schaffner survived her husband by nearly five years. She died on 11 April 1904 in San Francisco of fatty degeneration of the heart, at the age of 65. Her obituary in the San Francisco Call-Bulletin on 13 April 1904 described her as a "native of Oldenburg, Germany" and widow of the late Frederick Schaffner. She too was interred at Greenlawn Memorial Park in Colma, reunited with her husband in death.

His Children and Their Lives

Frederick Schaffner raised a total of six known children across his three marriages — one from his first marriage to Susanna Hoffman, and five from his second marriage to Martha Matilda. Together, they carried the Schaffner name forward in California and the Pacific Northwest.

• Herman Schaffner (1851–1921), Frederick's eldest, was born in New York and came west with the family. He married three times himself: first to Mary Ann Paul (born 1854, died 1908), with whom he had three children; then to Mary Jane McWhirter on 29 February 1912 in San Francisco; and finally to Fredericka Hartman on 30 August 1916, also in San Francisco. It was Herman's 1916 marriage certificate that recorded his parents' names as Frederick Schaffner and Susanna Hoffman, providing a vital genealogical link. Herman died on 8 December 1921 in San Francisco.

• Matilda Schaffner (born October 1857) married Lewellyn Augustus Bradford around 1876 and had two children. She lived a long life, dying in Alameda, California, on 24 June 1928 at approximately age 70.

• Frederick N. Schaffner (born August 1862) married Margaret Ann Ryan and had three children before his death on 5 April 1907 in San Francisco at around age 44.

• Louis Schaffner (born about 1864) appears in the 1870 and 1880 census records and then fades from the historical record. He died sometime after 1880 and before 1900.

• Charles Edwin Schaffner (born March 1867) moved to Oregon, married Louise A. Webber, and raised three children in Portland, where he died on 4 September 1916.

• Nellie Schaffner (1870–1933), the youngest, married Norman Richardson Arter in San Francisco in May 1888 and had three children. She outlived all her siblings, dying in San Francisco on 18 November 1933.

Frederick Schaffner, the immigrant cook from Darmstadt who became a saloon keeper and Freemason in San Francisco, lives on through his descendants — a tangible link between the Old World and the New.
