Before the formation of the Tennessee Walking Horse Heritage Society in 2003, and its subsequent definition of what marks  a Heritage Walking Horse in our Society, all of the Heritage breeders had crossed some of their mares with stallions that  were popular in their respective areas of Tennessee, or in some cases, within the larger breed group. Although none of the stud colts were retained for  breeding purposes, a number of the mares proved to be excellent producers of quality pleasure stock, and  are still used within the broodmare bands of the farms where they were foaled. Since the foals of these mares can never be established as Heritage Walking Horses due to their modern bloodlines, their offspring are being offered on this page as  Heritage Outcrosses. These foals and mature horses are blessed with the nice walking gaits and gentle dispositions  of their   Heritage parent, but their bloodlines are not as unique, as they are found more readily throughout the Tennessee Walking Horse breed.
