​Dutchman's sire was Le Mexico, the full brother of Furioso II.  Mexico served in the French National Stud where he became the sire of showjumpers like Rambouillet (Grand Prix, Vienna), Rush du Camp (Olympic Games, Mexico City) and Jexico du Parc (Olympic Games, Los Angeles). By 1996, after his thirteenth season at stud, Le Mexico was upgraded by the KWPN executive committee as a ‘keurhengst’. That title means an important step on the road towards an outstanding breeding career. After the first approval, judged on conformation and movement in hand, Dutch stallions have to fulfil the performance test. After successfully completing the performance test they are transferred into the ‘real’ studbook. But shortly after his upgrade he suffered a bout of colic and died. In the year of his death, the first edition of the breeding values was printed and Le Mexico ranked with 146 points in the jumping section alongside such famous performance sires as Nimmerdor, Abgar xx, Exkurs xx, Lucky Boy xx, Farn and Notaris. Le Mexico produced not only breeding stock – there are international showjumpers and dressage competitors for example, Alanda (ridden by Peter Kersten), Bollvorm’s Red Boy (Roelof Bril) and Mexican (Tineke Bartels).
