And Lord Clifden was the sire of Hampton.

In Thoroughbreds, it is recognized that Northern Dancer, by
Nearctic, by Nearco, is able to create winners from all male
duplications. This is known as the Northern Dancer “diversion”.
In Holstein we could similarly have the “Cor de la
Bryere Diversion” and to a slightly lesser extent, the
“Ladykiller Diversion”. We will come back to the reasons for
this. Females in the breed can generally cope with all male
duplications better than males. The successful Selle Français
breeding stallion Quidam de Revel, fourth in the Barcelona
Olympics, is an example of another stallion that has been successful
with exclusively male duplications, having three crosses
to the stallion Orange Peel, (5x5x5), in his pedigree, all through
sons. He is therefore somewhat of a contradiction to many of
these “rules”. Orange Peel is line bred to Galopin, the father of
St. Simon, 5s x 5d, and to Hampton 5s x 4s. These are, in fact,
the only aspects of linebreeding in Quidam’s pedigree, and they
are back in the fifth remove and the ninth and tenth remove.
However, there is another feature of this pedigree, namely Sonin-
Law through a daughter, that we will examine later, that may
explain why this horse has been so successful as a cross in
Holstein.
In Thorough-breds, all-male duplications in the first two or
three removes turn sprinters into stayers. The Thorough-bred
racehorse Count Chivas has a speedy calculated dosage index.
However, he was a marvelous endurance horse, able to go the
distance, as he carried Star Kingdom up front three times
through sons. This presence slowed him down considerably--
but gave him great staying power.
