Going back this far in time you aren't that many generations removed from the origin of the thoroughbred (which was the early 1700s), therefore there is less gene pool and more chance you will have multiple duplications of the same horse going back 5 or 6 generations. I am interested to know what your association with this horse is?

[HH88 23]

Your point regarding the smaller gene pool back then is well made particularly with relatively little cross border movement of breeding stock by todays standard. The question remains are the principals of breeding any different today than then? Previous HH88 posts suggest stallions have a strongest line (or lines) and appear to get their most successful progeny when mated with mares carrying an opposite strain of that line. The hard part is determining what that line is. Kincsems multiple linebreeding to different ancestors make it difficult to determine what is effective and what is incidental linebreeding. She was Cambuscans best filly, next post will look at his best colt.  

[HH88 23]

Whilst at stud in England (before departing for the Hungarian National Stud where he sired Kincsem) Cambuscan got Camballo winner of the Champagne  Stakes, July Stakes and the 2000 Guineas. From a completely different dam line to Kincsem the duplications in Camballos pedigree are remarkably similar. Of particular note the linebreeding to Haphazard and his full sister is repeated here. Perhaps even more striking Camballos line of Haphazards sister comes through Bustard. With Kincsem this line comes through Fanny Legh - who just happens to be a full sister to Bustard.

Of interest: Little Lady won the last race (1/4 mile) for yearlings run under the Jockey Club Rules. Ran between 30 and forty times. Winner of sixteen races in all from one to five-year-old. At age of sixteen produced 2000 Guineas winner Camballo.
