Boyar scions (Russian: дети боярские, сыны боярские; transliteration: deti/syny boyarskie) were a rank of Russian gentry that existed from the late 1300s through the 1600s. In the late 1700s—early 1800s descendants of the boyar scions who failed to prove nobility or regain it through the Table of Ranks were enrolled within the social group named odnodvortsy.
