Woltyzer was the sire at Janiszowka (per Shagyadata.ch) or at Uzin Stud - Poland, also owned by the Barnickis (Britta Fahlgren book) of one purebred Arabian foal. This foal, Vasco De Gama 1885, was the sire of Van-Dyck (Wan Dick), a very influential horse in Spanish Arabian pedigrees.

Note: Bazakoni.pl, a Polish horse pedigree database, gives Woltyzer's birthdate as 1869, and mentions an alternate name: Woltyżer / Voltijera.
