Question: What was the name of the sire of the specific breed of flaxen gene horse first bred in 1874 particularly known for their hardiness?

<P0-S0> The Haflinger, also known as the Avelignese, is a breed of horse developed in Austria and northern Italy (namely Hafling in South Tyrol region) during the late nineteenth century. <P0-S1>  Haflinger horses are relatively small, are always chestnut in color, have distinctive gaits described as energetic but smooth, and are well-muscled yet elegant. <P0-S2>  The breed traces its ancestry to the Middle Ages; there are several theories for its origin. <P0-S3>  Haflingers, developed for use in mountainous terrain, are known for their hardiness. <P0-S4>  Their current conformation and appearance are the result of infusions of bloodlines from Arabian and various European breeds into the original native Tyrolean ponies. <P0-S5>  The foundation sire, 249 Folie, was born in 1874; by 1904 the first breeders' cooperative was formed. <P0-S6>  All Haflingers can trace their lineage back to Folie through one of seven bloodlines. <P0-S7>  World Wars I and II, as well as the Great Depression, had a detrimental effect on the breed, and lower-quality animals were used at times to save the breed from extinction. <P0-S8>  During World War II, breeders focused on horses that were shorter and more draft-like, favored by the military for use as packhorses. <P0-S9>  The emphasis after the war shifted toward animals of increased refinement and height. <SEP> <P1-S0> The Mérens or Cheval de Mérens, still occasionally referred to by the older name of Ariégeois pony, is a small, rustic horse native to the Pyrenees and Ariégeois mountains of southern France, where the Ariège River flows, and northern Spain, near Andorra. <P1-S1>  Two general types, a small, light traditional mountain horse and a taller, sportier modern type, are found. <P1-S2>  Always black in color, Mérens must meet strict physical standards in order to be registered in the stud book. <P1-S3>  The breed is known for its sure-footedness on mountain terrain, as well as for its endurance, hardiness and docility. <P1-S4>  The French breed registry organizes regional offices, and partners with other national organizations in Europe to preserve and promote the breed. <P1-S5>  The organization enforces rigorous selection of breeding stock, with a goal of increasing quality in the breed. <P1-S6>  In the past, the Mérens was used for farm work, draft work and as pack horses. Today it is mainly used as a saddle horse, although some members of the breed have been successful in carriage driving. <P1-S7>  Many Mérens are taken on an annual transhumance (seasonal migration), in which they are moved higher in the mountains during the summer and into the valleys for the winter. <P1-S8>  An old practice, it fell into disfavor, but has recently re-emerged. <SEP> <P2-S0> The Rocky Mountain Horse is a horse breed developed in the state of Kentucky in the United States. <P2-S1>  Despite its name, it originated not in the Rocky Mountains, but instead in the Appalachian Mountains. <P2-S2>  A foundation stallion, brought from the western United States to eastern Kentucky around 1890, began the Rocky Mountain type in the late 19th century. <P2-S3>  In the mid-20th century, a stallion named Old Tobe, owned by a prominent breeder, was used to develop the modern type; today most Rocky Mountain Horses trace back to this stallion. <P2-S4>  In 1986, the Rocky Mountain Horse Association was formed and by 2005 has registered over 12,000 horses. <P2-S5>  The breed is known for its preferred "chocolate" coat color and flaxen mane and tail, the result of the relatively rare silver dapple gene acting on a black coat, seen in much of the population. <P2-S6>  It also exhibits a four-beat ambling gait known as the "single-foot". <P2-S7>  Originally developed as a multi-purpose riding, driving and light draft horse, today it is used mainly for trail riding and working cattle. <SEP> <P3-S0> The flaxen gene is a genetic mechanism that causes the mane and tail of chestnut-colored horses to be noticeably lighter than the body coat color, often a golden blonde shade. <P3-S1>  Certain horse breeds such as the Haflinger carry flaxen chestnut coloration as a breed trait. <P3-S2>  It is common in chestnut-colored animals of other horse breeds that may not be exclusively chestnut.
