History & Origin
Isaac comes from the Hebrew Yitzchak, 'he laughs', the son of Abraham and Sarah in Genesis; the name recalls Sarah's laughter at the promise of a child. It has been a steady boys' classic for centuries in Jewish, Christian and Muslim traditions alike. Girl use is a very rare outlier, and we flag the strong boys' lean (said 'EYE-zik').
For girls it barely registers in the U.S., against very heavy boys' use. Biblical, warm, and steady.
