Meaning & origin
Sierrah is a modern respelling that entered U.S. birth records in 1986, placing it among the newer wave of creative name variants. Its peak came in 2001, when it reached its highest rank. Since then, its trajectory has been steadily falling, reflecting a broader shift away from invented spellings of established names like Sierra. Sierrah's debut coincided with the rise of elaborate respellings in the late 20th century, though it never became common enough to appear in any state's top names lists. Parents drawn to Sierrah typically appreciate the familiar, nature-inspired sound of Sierra but want a distinctive spelling that sets their child apart.
Sierrah is a modern coinage that first appeared in the United States in the late 1980s. It respells the name Sierra, which is the Spanish word for 'mountain range,' probably under the influence of names such as Sarah or the Irish Ciara. The variant Sierrah has never reached high popularity, appearing modestly during the early 2000s before declining.
