From 1875 through the end of the century, black jockeys dominated the sport of Thoroughbred racing. In 1875 Oliver Lewis won the first running of the Kentucky Derby aboard Aristides. In 1892 Lonnie Clayton became the youngest jockey to win the Derby at age 15. In his first six races, at age 13, James Perkins earned five wins and one place at the Kentucky Association Race Track in Lexington. In 1898 Willie Simms became the only black jockey to win all three races of the Triple Crown. And then there was Isaac Murphy.

Isaac Burns Murphy (1861−1896) won the Kentucky Derby three times, the Latonia Derby five times, and four of the first five runnings of the American Derby, the premier race of his day. Murphy still holds the highest official winning percentage among all jockeys at better than 34 percent—539 winners in his 1,538 mounts. He also became the highest paid jockey of his era—the $12,000 he earned in 1887 is the equivalent of nearly $400,000 today. Murphy was the first jockey to be inducted into the National Museum of Racing and Hall of Fame at its creation in 1955. These accomplishments are all the more remarkable for someone who was born into slavery. Had Murphy not died at the young age of 35, he might have achieved much more.
Local interest in Murphy stems in part from claims that he was born in Clark County. The latest word comes from a March 26 Winchester Sun article, “Newly established Racing Hall of Fame of Fame coming to Winchester.” One of the Hall of Fame’s goals is “making the Isaac Murphy homeplace in Clark County a Kentucky tourist attraction.” Proving Isaac Murphy’s homeplace might be a challenge.
According to a Lexington newspaper obituary, Murphy was born on Upper Street in Lexington. The Kentucky Center for African American Heritage puts his birth in Bourbon County, and the Kentucky Derby Museum has it in Clark County. Interestingly, the National Museum of Racing and Hall of Fame lists his birthplace as Frankfort.
No evidence was provided for any of the above claims. Taking a look at first-hand accounts, we face similar problems. But first a little background information is needed.
Isaac’s mother was America Murphy, a daughter of Green and Anne Murphy. America married Jerry Burns alias Skillman in Bourbon County on December 28, 1859. Jerry enlisted in the Union Army in 1864 and died at Camp Nelson barely a month later. America’s application for a widow’s pension stated that Jerry Burns was the father of her only child, Isaac Burns, born January 2, 1861. After Isaac won his first race in 1876, he added Murphy to the end of his name.
Among the people who should know where Isaac was born, we find conflicting accounts.
In 1869 two women submitted statements in support of America’s pension application, one of whom was her sister—Anna Murphy and Anna Tucker. According to the statement, “They were present at the birth of said child Jerry, that he was born on the 2d day of January 1861 at the house of Col. John Brown in the county of Bourbon.” (It appears that America named her son Jerry at first, then in 1870 changed it to Isaac.)
In an 1889 interview with a St. Louis reporter, Isaac himself stated, “I was born in the city of Lexington and raised there and Cincinnati.”
These two accounts are in conflict, and neither one points to Clark County as the birthplace of Isaac Murphy. Clark County gets into the picture in a roundabout way.
Following Isaac’s death, his friend, turfman Llewellyn P. Tarlton, penned a memorial in the Thoroughbred Record, which opened with the following statement: “Isaac Burns, or as he is known to fame, Isaac Murphy, who was born in 1861, before the emancipation of his people, on the farm of Mr. David Tanner in Fayette County, Ky.”
The reasoning has gone like this: There was no David Tanner living in Fayette County, but there was a David Tanner in Clark County. According to the 1860 census, David Tanner was a wealthy farmer living a few miles east of Winchester on the south side of Ironworks Road. A second record was found that lists the birth of an unnamed male slave on David Tanner’s farm on January 6, 1861.

If we accept that Tarlton really meant David Tanner of Clark County rather than Fayette, and that Isaac’s reported birth dates (January 2 and 6) are reasonably close, then we have a circumstantial case for Isaac’s birthplace.
There is some evidence weighing against the claim, besides the statements of America’s sister and Isaac himself. There is no record that Tanner had a slave named America. In 1860 he owned seven enslaved people. Tanner died in 1862 and his estate inventory lists six—Hester, 65; Jack, 35; Una, 23, with children 5 and 2; and Hester, 5, an orphan. One other, Mary, died in 1861. No America was listed.
Sadly, we may never have a definitive answer to the question of Isaac Murphy’s birthplace. Federal, state and county recordkeeping for African Americans during the entire 19th century was abominable. In the antebellum period the US census only listed slaves by sex and age; names were omitted. Owners treated slaves as property—they didn’t list their cattle by name either—and listing names in the census might imply that slaves were actually people rather than property. After Emancipation recordkeeping for blacks in Kentucky was, at best, lackadaisical.
In conclusion, there is good but not incontrovertible evidence that Isaac Murphy was born in Clark County. However, no additional confirmation is needed to establish his standing near the top of Thoroughbred racing in America.
Two recent biographies of Isaac Murphy address the question of his birthplace: Pellom McDaniels, The Prince of Jockeys (University Press of Kentucky, 2013) and Katherine C. Mooney, Isaac Murphy (Yale University Press, 2023).
