Need help finding info on sire

Hi everyone! I've recently purchased a 1 and a half year old Dutch Warmblood/TB. She's a foal of Karsh (Secret Secretary). I've read somewhere that he is a deceased member of the Canadian Equestrian Team. Is this true? Does anyone know any info about him? Thanks in advance! :)

I found his pedigree...

And an another reply on a different forum about him.

Okay, thanks a lot! :)

Wb /tb crosses are popular in many sport horse disciplines. They are huge and showy and athletic. I have one out of KWPN stallion Odin. He's a pistol LOL and HUGE! But kind and easy going on the ground.

How big is your baby going to be?
