Sinai is the first foal from the mare Gørklintgårds Wilona by Quaterback / Don Schufro, and he is the fifth generation of one of Jørgen's old dam lines.

This dam line has produced the Grand Prix gelding Latino (Kayce Redmond/Karen Lipp) that won Brentina Cup and a regional championship in 2010 and the Intermediaire mare Gørklintgårds Denise (Katja Kavanagh), as well as the stallion Lord Walentin that was selected for the licinsing and Danish Warmblood's Elite Spring Auction, the silvermedal mare Wenche and  Trøstruplunds Roma'no that competes in international junior level dressage with Rie Wichmann in the saddle.

Sinai has three superior gaits - uphill and very functional.
