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?

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.  Haflinger horses are relatively small, are always chestnut in color, have distinctive gaits described as energetic but smooth, and are well-muscled yet elegant.  The breed traces its ancestry to the Middle Ages; there are several theories for its origin.  Their current conformation and appearance are the result of infusions of bloodlines from Arabian and various European breeds into the original native Tyrolean ponies.  The foundation sire, 249 Folie, was born in 1874; by 1904 the first breeders' cooperative was formed.  All Haflingers can trace their lineage back to Folie through one of seven bloodlines.  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.  Haflingers, developed for use in mountainous terrain, are known for their hardiness.  During World War II, breeders focused on horses that were shorter and more draft-like, favored by the military for use as packhorses.  The emphasis after the war shifted toward animals of increased refinement and height. <SEP> The Rocky Mountain Horse is a horse breed developed in the state of Kentucky in the United States.  Despite its name, it originated not in the Rocky Mountains, but instead in the Appalachian Mountains.  A foundation stallion, brought from the western United States to eastern Kentucky around 1890, began the Rocky Mountain type in the late 19th century.  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.  In 1986, the Rocky Mountain Horse Association was formed and by 2005 has registered over 12,000 horses.  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.  It also exhibits a four-beat ambling gait known as the "single-foot".  Originally developed as a multi-purpose riding, driving and light draft horse, today it is used mainly for trail riding and working cattle. <SEP> 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.  Two general types, a small, light traditional mountain horse and a taller, sportier modern type, are found.  Always black in color, Mérens must meet strict physical standards in order to be registered in the stud book.  The breed is known for its sure-footedness on mountain terrain, as well as for its endurance, hardiness and docility.  The French breed registry organizes regional offices, and partners with other national organizations in Europe to preserve and promote the breed.  The organization enforces rigorous selection of breeding stock, with a goal of increasing quality in the breed.  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.  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.  An old practice, it fell into disfavor, but has recently re-emerged. <SEP> 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.  Certain horse breeds such as the Haflinger carry flaxen chestnut coloration as a breed trait.  It is common in chestnut-colored animals of other horse breeds that may not be exclusively chestnut.
