Yankee Sullivan (born James Ambrose; c. March 10, 1811 – May 31, 1856), also known as Frank Murray and James Sullivan, was a bare-knuckle fighter and boxer.
 He was a prizefighting champion from 1851 to October 12, 1853.
 He considered himself to be the inheritor of Tom Hyer's title, and lost any claim to that title after losing a fight to John Morrissey.
John Morrissey (February 12, 1831 – May 1, 1878), also known as Old Smoke, was an Irish American bare-knuckle boxer and a Dead Rabbits gang criminal leader in New York City in the 1850s and later became a Democratic State Senator and U.S. Congressman from New York, backed by Tammany Hall.
 Morrissey began his bare-knuckle boxing career after a confrontation with a man known only as "Chroel" who was notorious for troubling his fellow townsmen.
 Although Morrissey was on the bitter end of his first bare knuckle bout, his display of bravery and fortitude earned himself the respect and historical acknowledgment of his peers.
George "Country McCloskey" McCheester or John McCleester (fl.
 1841-1850) was an American bare-knuckle boxer and sportsman involved in the early history of pugilism and prize fighting in Old New York.
 A well known fighter in his youth, his 1841 bout with Tom Hyer at Caldwell's Landing reportedly lasted nearly 3 hours and went to 101 rounds before the "Pride of Chatham Square" seconds threw up the sponge.
 Considered one of the greatest fights in the city's history, Hyer was recognized as the top fighter in the United States and awarded the American heavyweight championship.
 He and Yankee Sullivan were part of a group of promoters arrested following the death of boxer Thomas McCoy who died during a match against Christopher Lilly in Westchester County on September 13, 1842.
 Sullivan, who was the main promoter, was sentenced to two years in prison while McCleester and the others received light jail sentences or fines.

 Donny Adams's second for the fight was an Ex RAF policeman named Huw Rees.
 This fight was banned, but must have taken place later, as Shaw was reported later to have beaten Adams.
 Shaw won the bout in the first round.
 Before that fight Adams had 48 bare knuckle fights and won them all.

 Sullivan rose to national prominence as a result of his victory while Mahan went into semi-retirement, taking part in numerous exhibition bouts during the 1880s.
 Mahan later toured the U.S. with Sullivan and became one of his chief sparring partners.
