50% GW. First registered with Hoekshors Danny as sire. After a blood type test by Stichting Bloedgroeponderzoek in Wageningen it was revealed that Hoekshors Danny couldn't possibly be the sire of Kantje's Sjonny. Sire was almost certain to be Golden Wonder (He. Imp. 61), so he was re-registered in the Dutch New Forest studbook with sire Golden Wonder.
