Spanker himself was by D'Arcy's Yellow Turk from a daughter of the Morocco Barb and Old Bald Pegg by an Arab horse from a Barb mare.
Careless was by Spanker from a Barb mare, so that Childers's dam was closely in-bred to Spanker.
Although called an Arabian, there is little doubt he was a Barb pure and simple.
He died in 1780, and among other progeny left two famous sons, Woodpecker (1773), whose dam was Miss Ramsden (1760) by Cade, son of the Godolphin Barb, but descended also on the dam's side from the Darley Arabian and the Byerly Turk, and Highflyer (1774), whose dam was Rachel (1763) by Blank, son of the Godolphin Barb from a daughter of Regulus, also son of the Godolphin.
Europe are descended from the dun type; with more or less admixture of Barb blood.
