What is "gohanna"

Gohanna (1790 – April 1815) was a British racehorse that was second to Waxy in the 1793 Epsom Derby and was a successful sire in the late 18th and early 19th century. Gohanna was initially referred to as "Brother to Precipitate" during his early racing career until he was officially named in 1795. Retired to stud at Lord Egremont's Petworth House in 1801 where Gohanna spent the entirety of his 14-year stud career, he sired numerous successful racehorses including the Derby winners Election and Cardinal Beaufort.
