Sandro Boy is one of the best jumping horses in the world. Under the saddle of Marcus Ehning he has jumped together an impressive list of achievements with the finals at the World Cup in Kuala Lumpur at its summit. Also in the stud he is unique because from his relatively few progeny there are already a few top horses and inspected stallions. The most eye catching of his offspring is Sabrina who is, also with Markus Ehning, successful at the highest GP level.
Isha, the mother of Kusijgje van het Russeltveld is from the Sijgjes bloodline nr 440.
From this direct family comes the national jumping horse La Salsa Sijgje (v.Gershwin)
Kusijgje gained second place at the provincial cup in Bocholt.
