Claudia is by Collins out of the full sister to Calvaro Z, Calvara. Claudia, like Czarina unarguably carries some of the best blood lines in Europe - being out of the full sister to the stallion Calvaro Z – European Silver medalist and Dutch Champion jumping horse. Calvaro Z has had many major grand prix wins, a European Championship medal and a fantastic performance at the Sydney 2000 Olympic Games. Claudia is retained by the stud as a brood mare and produces excellent foals one of which is the stunning mare currently ridden by David Dobson, Cashmere.
