Biblical Hebrew name (variant of Zillah) meaning 'shade' or 'shadow,' borne by a wife of Lamech in Genesis.
Zilah is a variant of Zillah, one of the earliest women named in the Book of Genesis. In chapter four, Zillah (צִלָּה, Tsillah in Hebrew) is one of the two wives of Lamech, a descendant of Cain, and the mother of Tubal-cain — traditionally identified as the first metalworker, the forger of bronze and iron — and of Naamah. The name Zillah derives from the Hebrew root meaning "shadow" or "shade," evoking coolness, shelter, and the dappled quality of light filtered through leaves.
It is a name from the dawn of recorded human genealogy, appearing in one of the oldest textual layers of Genesis. Despite its ancient origins, Zillah and its variants have had a quiet but persistent presence in English-speaking naming traditions, particularly among Puritan and nonconformist communities of the seventeenth and eighteenth centuries who favored obscure Old Testament names as a form of theological seriousness and distinctiveness. The name appeared in English parish records and later in American colonial records, never common but never fully absent.
George Eliot used the name for a minor character in Middlemarch, and Emily Brontë gave it to the housekeeper at Wuthering Heights — both usages placing it in a world of practical, grounded women. Zilah, with its single-l spelling, sharpens the name's lines slightly, giving it a more contemporary silhouette. In an era when parents are reaching further back into biblical history for unusual names with genuine antiquity — Zipporah, Selah, Tirzah — Zilah fits naturally.
It carries the elemental poetry of its meaning: shade, shadow, the cool side of the rock. It is a name that whispers rather than announces itself.
