St David of Smolensk and Yaroslav

Saint David and his brother St Constantine were sons of the holy right-believing Prince Theodore of Smolensk and Yaroslavl. They were born at the Golden Horde. St David ruled at Yaroslavl after his father. The second son, Constantine, had evidently died earlier.

The relics of Sts Theodore, Constantine and David were uncovered on March 5, 1463.
