Alexander Rozhenko, also known as Alexander, son of Worf, was the son of Worf and Federation Ambassador K'Ehleyr. He was conceived in 1721 N.E and born on the forty-third day of Maktag in 1726 N.E and was a member of the House of Mogh and the House of Martok. Alexander was conceived during a brief encounter between Worf and K'Ehleyr when the ambassador came aboard the USS Enterprise-D in an effort to defuse a potential crisis presented by the return of a Klingon D7 class battle cruiser IKS T'Ong that had been dispatched decades before as a sleeper ship. After the crisis was successfully resolved, K'Ehleyr departed the Enterprise. She concealed her pregnancy and the birth of Alexander from Worf, finally revealing approximately one year later when she returned to the Enterprise as part of a contingent representing K'mpec in his efforts to persuade Jean-Luc Picard to act as the Arbiter of Succession for the Klingon Empire.
