Leading British sire in 1924 and 1930
Son-in-Law founded arguably the greatest dynasty of stayers this century. Since breeders of steeplechasers are always keen on good staying blood, it is not surprising that Son-in-Law can be found in many good chaser pedigrees. He also left a major mark on thoroughbred breeding in New Zealand, where his son Beau Pere was two time champion sire, and where his grandson Foxbridge was the leading sire for an incredible eleven seasons, from 1941 to 1951.
It is particularly interesting that the incidents of leading sires who are linebred to Dark Ronald and Son-in-Law is highest in Holstein. Household names who were linebred to Dark Ronald are Cor de la BryŤre, Landgraf I and Lord - in other words, the studbooks most prolific sire-makers. Cor de la BryŤre was linebred 5 x 5 to Dark Ronald through Rantzau and Furioso, Lord 5 x 6 through Cottage Son and Ladykiller, and Landgraf I 6 x 6 through Ladykiller and Anblick. Among the studbooks more recent stars, Calando I, Caletto I and Caletto II were linebred 5 x 6 x 6 to Son-in-Law
