Another prominent stallion was a coach horse stallion of unknown lineage named Blaze. Written pedigrees were kept of these foals beginning in the early nineteenth century, and in 1806, a filly, later known as "Lampits mare" after the farm name of her owner, was born that traced her lineage to the black stallion. This mare is listed in the ancestry of almost every Clydesdale living today. One of her foals was Thompson's Black Horse (known as Glancer), which was to have a significant influence on the Clydesdale breed.
