Sabine refers to the Sabines — an ancient Italic people who lived in central Italy in the area now around Rome. The famous Roman "Rape of the Sabine Women" (the abduction of Sabine women by the first Romans, who needed wives) is one of the founding myths of Rome.
Sabine is popular in France, Germany, and Belgium. In the U.S. it is rising slowly. Two soft syllables, three thousand years of Italian history behind them.
Sabine reduces to seven — the number of ancient legend.
