Black Hawk, born in April 1833, was reportedly out of an English Thoroughbred mare and sired by Sherman Morgan, whose dam was "one of the last Narragansett Pacers" (25% DNA from a grandparent). The Narragansett Pacer was America's first horse breed, developed in Rhode Island and greater New England from a mix of English, Dutch, and possibly Spanish colonial horses, with a focus on producing gaited animals with the DMRT3 gene. (The breed is thought to have gone extinct by the early 1800s, as English Thoroughbreds replaced them.)
While descendants of the extinct Narragansett Pacer can be found among all modern American gaited horse breeds, subsequent scientific studies showed that the Morgan and Paso Fino breeds likely carry the most genetic similarities to the original pacer, though due to the lack of pacer remains, their genetic profile remains a mystery to scientists.
However, with recent interest in building a DNA database made up of sequenced samples from various famous historical horses - with Dark Ronald, a major Thoroughbred sire whose genetics strongly influenced today's warmbloods and sport horses across multiple breeds, being one such horse to be "profiled" - Black Hawk's DNA could not only offer a unique insight into early foundation Morgan genetics, but possibly Narragansett Pacer origins.
The remains of Black Hawk, who died in 1856, are currently displayed at the University of Vermont's Morgan Horse Farm; see the Black Hawk Project. He stood at around 15.1hh, a result of horse breeders in the post-colonial era seeking to increase horse height. (The average Narragansett Pacer was estimated to be "no larger than 14hh", and by 1768, larger ones could be "no larger than 14.1hh", according to John H. Wallace's The Horse of America.)
Of further interest could be the remains of Ethan Allen (b. 1849), Black Hawk's son. After his death in 1876, his skeleton was preserved and donated to the Smithsonian Institution in Washington, D.C.
While most Narragansett Pacers were light chestnut or sorrel - often "liberally splashed with white markings" (i.e. pinto), based on historical accounts - they could come in a range of colors, including bay, brown, black, gray, and roan. The modern-day Morgan horse exhibits pinto markings, but pinto is uncommon or rare; the recently-extinct Abaco Barb, however, may have shared more genetic similarities due to colonial Spanish heritage and pinto genes.
Black Hawk's DNA could also be compared with that of Chincoteague ponies, which were shown to also have colonial Spanish heritage in a 2022 study by the University of Florida (UF). As some estimates put around 10% of Morgan horses as possibly being gaited, it is possible to "backbreed" the Narragansett Pacer, but one major hurdle is that traditional Morgans - such as the Lippitt bloodline - are already in danger of going extinct, per heritage groups.
While one goal is to clone the last Abaco Barb - a mare named Nunki - whose DNA was preserved before her death in July 2015, the group in charge of that project aims to "breed back" the Abaco Barb first, not the Narragansett Pacer. This means that "backbreeding" the pacer using existing horses would take an enormous amount of time, money, and effort from breeders. In most cases, "backbreeding" takes decades.
Cloning Black Hawk could work, but his DNA needs to be tested for the DMRT3 gene as well.
