William Rockefeller Sr. was John D. Rockefeller’s father, a traveling patent-medicine seller and trader who lived from 1810 to 1906. He also used the name Dr. William Levingston and became known as “Devil Bill.” However, he was not the William Rockefeller who co-founded Standard Oil.
That distinction matters because online biographies often merge two men. William Avery Rockefeller Sr. was the father, while William Avery Rockefeller Jr. was his son and John D. Rockefeller’s business partner. Therefore, Standard Oil titles, railroad investments, a 1922 death, and reports of a roughly $100 million estate belong to William Jr., not William Sr.
For readers checking records, the dates resolve the problem quickly: the father died in 1906, while the oil executive lived until 1922. Moreover, a source describing Standard Oil leadership almost certainly concerns the son, even when its title simply says William Rockefeller.
Who Was William Rockefeller Sr.?
A background biographical overview identifies the subject as William Avery Rockefeller, an American trader, traveling salesman, and self-styled botanical physician. He sold patent medicines and pursued other ventures, including lumber, land, horses, and private lending. Later, he lived for long periods under the surname Levingston.
He is historically important mainly because two of his sons, John D. Rockefeller Sr. and William Avery Rockefeller Jr., helped build Standard Oil. Nevertheless, William Sr. never held the company roles associated with his younger namesake.

What Did William Rockefeller Sr. Do for a Living?
William worked primarily as an itinerant seller and trader. Accounts describe him marketing patent medicines while calling himself a “botanic physician” or “herbal doctor.” However, publicly available evidence does not confirm formal medical education or a recognized license.
He also pursued several kinds of commerce. Biographies associate him with lumber, horses, real estate, salt, and private loans. Consequently, “businessman” is accurate only in a broad nineteenth-century sense; he did not build or manage a large corporation.
The market in which he sold remedies had few of today’s consumer protections. In fact, the federal 1906 Food and Drugs Act arrived only weeks after his death and initially focused on adulteration and misleading labels. Therefore, calling him a patent-medicine seller describes a loosely regulated trade, not verified medical practice.
Why Was William Rockefeller Sr. Called “Devil Bill”?
Neighbors and later biographers used “Devil Bill” to capture William’s reputation as a charming but unreliable operator. He traveled without a predictable schedule, displayed cash when he returned, sold sweeping cures, and kept parts of his life hidden.
However, the nickname is evidence of reputation, not proof of every anecdote later attached to him. Stories about elaborate shooting displays, horse theft, disguises, and specific remedy ingredients often appear without accessible primary documentation. Therefore, a careful biography should not treat all of them as established facts.
Was “Dr. William Levingston” Really a Doctor?
No reliable source reviewed for this article confirms that William held a medical degree or recognized professional credential. Instead, sources describe “Dr. William Levingston” as a name and title he used while selling botanical remedies.
That difference is important. Although nineteenth-century sellers often adopted medical language, a claimed title did not necessarily reflect regulated training. As a result, the safest description is “self-styled doctor” or “patent-medicine seller.”
How Did William Rockefeller Sr. Influence John D. Rockefeller?
William gave John practical exposure to bargaining, recordkeeping, lending, and risk. In his memoir, John wrote that he owed his father a debt for training him in practical ways. Nevertheless, John’s disciplined habits and religious outlook also reflected the much steadier influence of his mother, Eliza.
The clearest financial link came in 1859. The official biography of John D. Rockefeller says John combined $1,000 of his own savings with $1,000 borrowed from his father to form a produce partnership with Maurice B. Clark.
John supplied more detail in Random Reminiscences of Men and Events. He recalled that his father advanced the $1,000 before John turned 21 and charged 10 percent interest, a rate John said was common for private loans at the time. Later, John also remembered receiving additional loans at the same rate.
However, the loan did not make William Sr. a Standard Oil founder. John entered oil refining in the 1860s and organized Standard Oil with William Jr. and other partners in 1870. Therefore, William Sr.’s role belongs to John’s early business education, not the oil company’s management.
Family and Relationships
Marriage to Eliza Davison
William married Eliza Davison in Niles, New York, on February 18, 1837. Eliza raised the family during William’s frequent absences and became the household’s stable religious influence.
Together, they had six children: Lucy, John Davison, William Avery Jr., Mary Ann, Franklin, and Frances. Frances died in childhood, while John and William Jr. later became the family’s best-known businessmen.
Nancy Brown and Two Reported Daughters
Biographers report that William had a relationship with Nancy Brown and fathered two daughters, commonly named as Clorinda and Cornelia. However, publicly available information about both daughters remains limited, and online family trees do not provide the same assurance as directly examined civil records.
Therefore, they should be identified as reported children rather than folded into Eliza’s household. This wording also prevents the common mistake of saying Eliza bore eight children.
Margaret Allen and the Levingston Identity
In the mid-1850s, William married Margaret L. Allen in Canada while Eliza was still alive. Sources disagree on whether the ceremony occurred in 1855 or 1856. Nevertheless, the overlap supports the historical description of his second marriage as bigamous.
William lived with Margaret under the Levingston name in several places. Meanwhile, Eliza remained legally connected to him until her death in 1889. The arrangement stayed largely outside public view during William’s lifetime.

What Is Verified About the 1849 Criminal Allegation?
Edited historical accounts report that William faced an 1849 indictment arising from a sexual-assault allegation in Cayuga County, New York. However, an indictment records an accusation and legal charge; it is not a conviction.
The available evidence reviewed for this article does not establish that a court convicted him. Therefore, accurate wording should say that he was accused or reportedly indicted. It should not present the alleged act as a proven criminal judgment.
Where Did William Rockefeller Sr. Live and Die?
William’s life crossed several states and territories. His family lived in upstate New York and later moved to Ohio, while William’s travels took him farther west. Moreover, National Historic Landmark documentation summarizes John’s early family setting.
Later, William spent time near Park River in Dakota Territory as Dr. Levingston. In addition, the North Dakota History index records a scholarly article about William Avery Rockefeller’s life in that area.
William died in Freeport, Illinois, on May 11, 1906. Because his November birthday had not yet occurred, he was 95, although some histories call him 96 or describe him as being in his 96th year. Accounts place his burial in Freeport’s Oakland Cemetery under the Levingston surname.
His exact birthplace remains less certain. Some sources say Ancram, while others name Granger or Grangerville, New York. Consequently, “born in New York” is the most defensible short answer unless a directly examined original record settles the locality.
William Rockefeller Sr. Net Worth: What Can Be Verified?
No authoritative financial source confirms William Rockefeller Sr.’s net worth, salary, income, or estate value. He handled money, owned or traded property, and made private loans; however, those facts do not support a precise modern estimate.
The most common confusion comes from his son. Reports of an estate worth roughly $100 million concern William Avery Rockefeller Jr., the Standard Oil financier who died in 1922. Therefore, that figure must not appear as William Sr.’s wealth.
What Is William Rockefeller Sr.’s Historical Legacy?
William’s legacy lies more in family history than in a company or public institution. His unsettled work, financial lessons, disappearances, and double life formed part of John D. Rockefeller’s early environment. However, John transformed those experiences through his mother’s discipline, his own bookkeeping habits, and later partnerships.
William also shows why historical identity control matters. A shared name can turn a traveling seller into a Standard Oil executive with a vast estate in just a few copied sentences. Consequently, good biography research must compare dates, relatives, occupations, and source quality before joining claims.
Moreover, comparing life dates before career details prevents the most damaging error: assigning one relative’s achievements, controversies, or fortune to another.
Finally, the surviving archival record gives researchers a path beyond folklore. The Rockefeller Archive Center holds family photographs and papers, while government and historical collections document places connected with the family. Ultimately, those records provide a firmer foundation than unsourced retellings.

Conclusion: Understanding William Rockefeller Sr.
William Rockefeller Sr. was a traveling seller, trader, and self-styled doctor whose hidden Levingston identity made him one of the Rockefeller family’s most unusual figures. However, the verified record is more precise than the legend: he influenced John D. Rockefeller’s early business education, but he did not found Standard Oil and has no confirmed net-worth figure.
Therefore, the clearest biography separates William Sr. from William Jr., labels allegations accurately, and acknowledges unresolved details. That approach preserves the compelling history without turning repetition into proof.
