Godolphin Arabian
Recent DNA studies disprove the theory that he was a Barb, as his descendants' Y-DNA traces to the same general haplotype as the Darley Arabian, though to different sub-groups and there are relatively few male-line descendants of the Godolphin Arabian today. This group may have been of Turkoman horse or Arabian origins, as modern horses of both breeds have been linked to this haplotype.
