Variant spelling of Sarah, from Hebrew meaning 'princess' or 'noblewoman'.
Sarrah is an elaborated spelling of one of the oldest personal names still in common use — Sarah, from the Hebrew *שָׂרָה* (Śārāh), meaning "princess," "noblewoman," or "lady of high rank." In the Hebrew scriptures, Sarai was the wife of Abraham, her name changed by God to Sarah as a mark of her new covenant identity and her destiny as the mother of nations. That biblical origin gave the name extraordinary staying power across millennia and cultures, carried into Christianity, Islam (where she appears as Sāra in the Quran), and Judaism alike.
The doubled *r* in Sarrah is an orthographic variation that appeared sporadically in English parish records from the seventeenth century onward, sometimes reflecting regional pronunciation, sometimes a scribe's personal choice, and occasionally a family's desire to distinguish their child from the many Sarahs around her. It gives the name a slightly antique, manuscript quality — as though it were lifted from an old family Bible or a handwritten census ledger. The underlying name Sarah has never truly gone out of fashion.
It dominated English-speaking naming charts for much of the eighteenth and nineteenth centuries, dipped in the mid-twentieth, and returned robustly in the 1970s and 1980s. The Sarrah spelling carries all of that heritage with a small twist of individuality — a way of honoring a deeply traditional name while giving it a quiet mark of distinction. It suits families who want something recognizable yet not quite identical to every other Sarah in the class.
