Dimitri (Mito) Jorjadze was born in the country of Georgia, Kakheti, to Alexander Jorjadze, a Georgian noble man, officer, diplomat and a winemaker, and his half Ukrainian-half Georgian wife - Domenica Naumenko.

Dimitri was a member of the Georgian nobility of Tbilisi from the Jorjadze family, who became exiled after the overthrow of Tsarist Russia and the subsequent Bolshevik takeover.

In early July 1931, he won the Touring Car Grand Prix, 24 Hours of Spa, in Belgium.

Most notable of his horses was Princequillo, which in 1943, was the fastest distance runner in the United States and which became a two-time Leading sire in North America and a seven-time Leading broodmare sire in North America.
