A Family History of the

Rudolf & Dorothea (Dinkel) Spangler Family

of York, Pennsylvania (1738–1835)

Introduction

The story of Rudolf and Dorothea Spangler is one of industry, patriotism, and deep community roots in the borough of York, Pennsylvania. Rudolf, a craftsman of rare skill, rose from silversmith and clockmaker to soldier, politician, and respected civic leader during the founding decades of the American republic. Dorothea, born across the Atlantic in Strasbourg, France, brought with her the heritage of a family that had already made its mark in Pennsylvania colonial life. Together, they built a household of eleven children and left a legacy that would endure for generations in York County and beyond.

Their lives spanned one of the most consequential eras in American history. Rudolf was born when Pennsylvania was still a British colony, served in the Revolutionary War, and lived to see the new nation establish its institutions. Dorothea outlived her husband by nearly twenty-four years, dying in 1835 at the remarkable age of eighty-seven—a testament to her remarkable fortitude. This family biography draws on the genealogical sketch compiled by Randall J. Seaver, as well as contemporaneous sources including census records, probate documents, and period newspapers.

Rudolf Spangler: Origins and Early Life

Rudolf Spengler (the family name was also spelled “Spangler” interchangeably in colonial records) was born in 1738 in York, York County, Pennsylvania Colony. He was the son of Johann Baltzer “Baltzer” Spangler (1706–1770) and Maria Magdalena Ritter (1706–1784), who had married in 1732 in Baden-Württemberg, Germany, before emigrating to the Pennsylvania Colony. Baltzer Spangler was among the wave of German-speaking immigrants who shaped the character of York County in the early eighteenth century, bringing with them their trades, their Reformed faith, and their family traditions.

Rudolf grew up as one of eight children in the Spengler household. York was a young but growing town—it had been laid out in 1741 and incorporated as a borough in 1787—and the Spangler family were woven into the fabric of its social and commercial life from the very beginning. His father Baltzer, who died in 1770, appears to have established the family firmly in York, where multiple generations would remain for over a century.

Rudolf’s Parents

Rudolf’s parents, Johann Baltzer Spangler and Maria Magdalena Ritter, married in 1732 in Baden-Württemberg before settling in York, Pennsylvania Colony, where they raised their family. Baltzer died in 1770 and Magdalena in 1784.

Rudolf’s Siblings

Rudolf was the fifth of eight children born to Baltzer and Magdalena Spangler:

• George Spengler (born 20 March 1732, Weiler, Rheinland-Pfalz; died 2 October 1810, York). He married Anna Maria Schultz about 1755 in York.
• Maria Juliana Spengler (born 25 October 1734, York; died 1770, York). She married Johann Frantz Wilhelm Bickle on 12 December 1757 in York.
• Johann Baltzer Spengler (born 16 April 1735, York; died 1 August 1798, York). He married Christina Messerschmidt before 1761 in York.
• Michael Spengler (born about 1737, York; died August 1793, York). He married Margaret Dinkel—notably a member of the same Dinkel family into which Rudolf himself would marry.
• Rudolf Spengler (born 1738, York) – the subject of this biography.
• Elizabeth Spengler (born 1740, York; died 25 November 1825, York). She married Francis Koontz on 5 November 1764 in Lancaster.
• Daniel Spengler (born about 1742, York; died about 1777, York). He married Maria Elisabetha Leightner on 29 December 1765 in York.
• John Spengler (born 29 June 1747, York; died 11 October 1796, York). He married Margaret Barth in 1777 in York.

Interestingly, the Spengler and Dinkel families were already intertwined before Rudolf and Dorothea’s marriage: Rudolf’s brother Michael married a Margaret Dinkel, and Dorothea’s sister Margaret Salome Dinkel married a Philip Caspar Spengler. These overlapping family ties were common in tight-knit German immigrant communities where a relatively small group of families formed the social and commercial core of a community.

Dorothea Dinkel: Origins and Early Life

Maria Dorothea Dinkel was born about 1748 in Strasbourg, Alsace, France—a city at the crossroads of French and German culture situated on the Rhine River at the border of modern France and Germany. She was the daughter of Johann Daniel Dunckel (1713–1755) and Maria Ursula Hornuss (1713–1793), who had married in 1735. The family emigrated from Strasbourg, likely during the 1740s or early 1750s, joining the large flow of German-speaking Alsatian and Palatine immigrants who settled in Pennsylvania—a journey of several weeks by ship across the Atlantic followed by travel inland to York County.

Dorothea’s father, Daniel, died in 1755 when she was just a young child, leaving her mother Ursula to raise the family. Ursula Hornuss Dinkel lived to 1793, long enough to see her children established in Pennsylvania society. The Dinkel family settled in York, where Dorothea grew up alongside her siblings in the same German Reformed community that the Spanglers called home.

Dorothea’s Parents

Dorothea’s father, Johann Daniel Dunckel, was born in 1713 and died in 1755 at the age of only forty-two, leaving her mother Maria Ursula Hornuss (1713–1793) to raise the children. Ursula lived to eighty years of age.

Dorothea’s Siblings

Dorothea was the youngest of six children born to Daniel and Ursula Dinkel in Strasbourg before the family emigrated to Pennsylvania:

• Margaret Salome Dinkel (born 6 April 1736, Strasbourg; died 29 June 1813, York). She married Philip Caspar Spengler about 1752 in York—another member of the Spengler family, drawing the two families into close kinship.
• Anna Maria Dinkel (born about 1738, Strasbourg; died 23 February 1797, York). She married Philip Albright about 1760 in York.
• Johann Daniel Dinkel (born 17 June 1741, Strasbourg; died 1812, Bridgewater, Rockingham, Virginia). He married Anna Margaret Ruhl before 1758 in York, before later moving to Virginia.
• Peter Dinkel (born 11 July 1742, Strasbourg; died 22 December 1827, York). He married Anna Elizabeth Wolfe on 15 February 1767 in York, just two weeks after Dorothea’s own wedding.
• Maria Catherina Dinkel (born 22 June 1746, Strasbourg; died 22 March 1831, York). She married David Candler on 30 October 1763 in York.
• Maria Dorothea Dinkel (born about 1748, Strasbourg) – the subject of this biography.

Marriage and Life Together in York

Captain Rudolf Spengler and Maria Dorothea Dinkel were married on 1 January 1767 at Trinity Reformed Church in York, Pennsylvania Colony. Rudolf was approximately twenty-eight years old and Dorothea was about eighteen. The marriage record appears in the church’s register, where their names are recorded as “Rudolph Spengeler” and “Dorothea Duenckel.”

The wedding day itself is immortalized in a charming anecdote: on the morning of his wedding, Rudolf went with his gun and deer hounds to Baumgardner’s Woods, a mile southeast of York, where he shot a deer to provide venison for his own nuptial dinner. The story speaks volumes about the man—self-reliant, vigorous, and thoroughly at home in the Pennsylvania countryside.

The couple settled in York, where they would spend the rest of their lives. It was a propitious time to build a life in York County: the borough was growing steadily, trade was flourishing, and the German-speaking community was well established. Rudolf’s craft skills, civic ambitions, and military service would place the Spangler name among the most respected in the region.

Rudolf’s Trades and Crafts

Rudolf Spengler was a silversmith and clockmaker by trade—skilled crafts that required both artistic talent and technical precision. As a silversmith he worked with precious metals, fashioning decorative and functional objects for the wealthier families of York. As a clockmaker, he crafted timepieces of lasting quality. When the historian Edward W. Spangler was researching his 1896 book The Annals of the Families of Caspar, Henry, Baltzer and George Spengler, he discovered three tall “grandfather’s clocks” still in existence that Rudolf had made, each bearing the inscription “Rudy Spengler, York town” on its dial. These surviving artifacts are remarkable testaments to his craft. By 1773 he had expanded his activities and was assessed as a merchant in York—a sign of growing prosperity and commercial ambition.

Revolutionary War Service

When war with Britain broke out in 1775, Rudolf Spangler did not hesitate. He became a member of Captain George Eichelberger’s Company in 1775 and was shortly afterward elected Captain of the Sixth Company of the York County Militia. This unit was part of the five York County battalions that marched to eastern New Jersey in 1776 to form the famous “Flying Camp”—a mobile reserve force of some ten thousand troops assembled by Congress to defend the Middle Colonies.

The Flying Camp saw significant action during the critical New York and New Jersey campaigns of 1776, a period of severe hardship for the Continental cause. Rudolf’s willingness to lead men into this dangerous theater of the war earned him the honorific title “Captain,” by which he was known for the rest of his life. This title was engraved on his gravestone, a mark of enduring honor.

Property and Civic Affairs

The U.S. Census of 1790 shows the Rudolph Spangler household in York Township with one adult male, eight males under the age of sixteen, and three females—a lively and full household reflecting his large family. By 1798, the Direct Tax List documents his substantial property holdings: he owned at least two houses (one a two-story brick house on West Market Street, the other unfinished), a stable, a barn, and a brick kitchen, as well as land parcels in York Township. The larger house was assessed at $1,750 and the second at $400—meaningful sums at the time.

Rudolf served as County Treasurer from 1801 to 1805. He was a State Senator and Burgess of York in 1803, and a member of the General Assembly of Pennsylvania in 1810—the year before his death. By 1805 he had patented lands in what is now Springgarden Township, and his property holdings extended across multiple lots on East Market, South Queen, King, and High Streets in York. His civic career, by any measure, was one of remarkable distinction for a man who had arrived in the world as the son of a German immigrant craftsman.

Their Children

Rudolf and Dorothea raised eleven children together in York, Pennsylvania. The family was a central part of York’s German Reformed community, and their children married into many of the county’s most prominent families.

• General John Jacob Spengler (born 28 November 1767, York; died 17 June 1843, York). Married (1) Susannah Hay on 5 May 1791 in York, seven children; married (2) Catherine Allen Hamilton on 23 May 1820 in Harrisburg, five children. He achieved the rank of General, continuing the family’s military tradition.

• Maria Catherine Spengler (born 1 January 1770, York; died 27 December 1824, York). Married George Augustus Barnitz in 1792 in York, seven children.

• Elizabeth Spengler (born 23 February 1773, York; died 14 April 1844, York). Married William Nes before 1793 in York, five children.

• Margaret “Recky” Spengler (born 14 March 1773, York; died 15 April 1852, Winchester, Frederick, Virginia). Married Joseph Slagle on 22 September 1807 in York, six children. She outlived her siblings, dying at age seventy-nine in Virginia.

• Jesse Spengler (born 5 July 1775, York; died 12 September 1860, York). Married Mary D. Heckert before 1798 in York, nine children. Jesse lived to the extraordinary age of eighty-five.

• Johannes Spengler (born 22 May 1777, York). No further records are noted for Johannes.

• Anna Maria Spengler (born about 1779, York; died 11 April 1816, York). Married Peter Schmahl on 27 April 1797 in York, four children. Anna Maria died relatively young at around age thirty-seven.

• Daniel Spangler (born 9 October 1781, York; died 19 July 1851, Georgetown, Beaver, Pennsylvania). Married Elizabeth King on 12 March 1815 in York, ten children. Daniel relocated to western Pennsylvania.

• Mary Margaret Spengler (born about 1783, York; died 1841, York). Married Martin Kieffer in 1804 in York, no children.

• Peter Spengler (born 16 May 1786, York; died 22 May 1823, York). Married Sarah Gardner on 15 October 1812 in York, four children. Peter died young at age thirty-seven, just eleven days after his birthday.

• Helen Dorothea Spengler (born 24 June 1789, York; died 15 May 1842, York). Married Charles Frederick Fisher on 2 October 1808 in York, four children.

Rudolf’s will, written around 1807 and proved on 26 August 1811, named four sons—Jacob, Jesse, Daniel, and Peter—and five daughters—Catherine (wife of George Barnitz), Elizabeth (wife of William Nes), Mary (wife of Peter Small), Margaret (wife of Joseph Slagle), and Magdalena (wife of Charles Fisher). Note that the will uses the given name “Magdalena” for what family records call Helen Dorothea—a reminder that informal names and legal names did not always agree in this era. The will left all of Rudolf’s estate to Dorothea for her lifetime, with the remainder to be divided equally among the children after her death. The document is a model of clarity and fairness, characteristic of the man himself.

Rudolf’s Final Years and Death

By the time of the 1810 Census—just a year before his death—Rudolf’s household had grown smaller. Most of his children had married and established their own homes. The census records show one man over forty-five, a younger man between sixteen and twenty-six, a younger woman in the same age range, and an older woman—likely Dorothea—still at home.

Rudolf Spengler died on 5 August 1811 in York, at approximately seventy-three years of age. His obituary, published in The York Recorder on August 10, 1811, captured the esteem in which he was held:

“Died, in this borough, at an advanced age, on Thursday last, Rudolf Spangler, Esq. The confidence reposed in the deceased by his fellow citizens in choosing him to serve in the State Senate and House of Representatives, are sufficient testimonials that in private and public life he was the honored and upright man. His remains were yesterday deposited in the German Reformed burying ground, attended by a long train of mourning relatives and friends.”

He was initially interred in the German Reformed burying ground, and was later buried alongside his wife at Prospect Hill Cemetery in York, where their shared gravestone still stands today.

Dorothea’s Long Widowhood and Death

When Rudolf died in 1811, Dorothea was approximately sixty-three years old. She would spend nearly a quarter-century more as his widow, living to the remarkable age of eighty-seven. Around 1815, a left-profile sketch of Dorothea was drawn, which was later preserved in a Spangler family history book—a rare and touching memento of a woman who had lived through the entire founding era of the American republic.

In 1834, at approximately eighty-six years of age, Dorothea penned her last will and testament entirely in her own hand and entirely in German—the language of her Strasbourg childhood and her York community. The will was authenticated in court after her death by local citizens who could verify her signature, a testament to the respect she commanded in the community.

Maria Dorothea Spangler died on 12 June 1835 in York, Pennsylvania. Her obituary, published in The York Gazette on June 18, 1835, remembered her with warmth and reverence:

“In memory of Dorothea Spangler, relict of Rudolf Spangler, deceased… How few they that arrive at that period of life, blessed with a happy temperament of mind. She led the life of a pure and upright Christian. Relatives and friends revere and cherish her memory.”

She was laid to rest beside her husband at Prospect Hill Cemetery in York. Their shared gravestone bears an inscription that is as simple and dignified as their lives:

Rudolf Spangler Born 1738 Died Aug. 5 1811 Capt. 1775

Dorothea Spangler Born 1748 Died June 12, 1835

Legacy and Historical Significance

The story of Rudolf and Dorothea Spangler is, in many ways, the story of early America itself. Rudolf’s father crossed the Atlantic as part of the great German migration that transformed colonial Pennsylvania; Rudolf himself fought in the Revolution and helped build the new nation’s institutions; and his children spread across Pennsylvania and beyond as the young country expanded. Dorothea brought a distinctly European heritage—born in Alsace, raised amid the French and German cultures of the Rhine borderlands—and grafted it onto the deeply rooted German-American community of York.

Their eleven children—who married into families named Barnitz, Nes, Slagle, Heckert, Schmahl, King, Kieffer, Gardner, and Fisher—wove the Spangler family into the very fabric of York County society. Son General John Jacob Spengler continued the military tradition his father had begun, rising to the rank of general. Son Jesse lived to eighty-five, long enough to see the Civil War threaten the union his grandfather had helped create.

The three grandfather clocks bearing the inscription “Rudy Spengler, York town” that still survived into the 1890s when genealogist Edward W. Spangler found them are perhaps the most evocative symbol of Rudolf’s life: handmade objects of lasting beauty and utility, built by a man who measured time carefully and used it well.
