Lavinia.
Daughter of Latinus, betrothed to Turnus, King of the Rutuli. When Æns landed in Italy, Latinus made an alliance with the Trojan hero, and promised to give him Lavinia to wife. This brought on a war between Turnus and Ænas, which was decided by single combat, in which Ænas was victor. (Virgil Æneid.)

Lavinia. The daughter of Titus Andronicus, bride of Bassianus, brother of the Emperor of Rome. Being grossly abused by Chiron and Demetrius, sons of Tamora, Queen of the Goths, the savage wantons cut off her hands and pluck out her tongue, that she may not reveal their names. Lavinia, guiding a stick with her stumps, makes her tale known to her father and brothers; whereupon Titus murders the two Moorish princes and serves their heads in a pasty to their mother, whom he afterwards slays, together with the Emperor Saturninus her husband. (Titus Andronicus, a play published with those of Shakespeare.)

In the play the word is accented Andronicus not Andronicus.
Lavinia. Italy; so called from Lavinia, daughter of Latinus and wife of Ænas. Ænas built a town which he called Lavinium, capital of Latium.
