About Marlon XX

Marlon XX is a (died 1981) bay showjumping stallion foaled in 1958, by Tamerlane XX out of a Fairford XX dam.

Marlon XX, born in 1958 in Ireland, was a Thoroughbred stallion of significant repute in the equestrian breeding community, particularly within the showjumping and dressage sectors. Despite not having a personal competition record in high-level showjumping or dressage, Marlon became a cornerstone stallion whose progeny excelled in sporting arenas. Breeder H. Kerr Esquire facilitated his birth, setting the stage for Marlon's extensive influence in equestrian lineage.

Marlon XX's pedigree includes notable Thoroughbred ancestors such as Nearco XX through his paternal lineage, making him a desirable sire in sport horse breeding circles. He was widely recognized for transmitting athletic prowess to his offspring, contributing notably to the development of dressage lines that achieved significant success, such as his progeny's achievements in European and Olympic Championships during the early 1980s.

Throughout his breeding career from 1965 to 1981, Marlon XX was primarily stationed in major European studbooks, including the Swiss Studbook. This endorsement by multiple studbooks emphasized his value and conformation as a premium sire. Posthumously, his impact is still visible in the successes of descendants who participate in top-level showjumping competitions worldwide.

Although Marlon XX's direct contribution to 1.60m level showjumping is not exhaustively documented, his extended influence is palpable. Through mares like Dan Salina, he sired progeny that achieved significant milestones within the sport. Marlon XX's genetic legacy continues to appear in the pedigrees of contemporary showjumpers and eventers, underscoring his lasting significance in the sport horse breeding sector.
