Reill is Irish in Origin.

Reill is a contemporary, streamlined respelling of the Irish surname Reilly/Riley, ultimately from Ó Raghallaigh, “descendant of Raghallach.” The personal name Raghallach is interpreted as “valorous” or “courageous,” though its exact etymology is debated; an alternative pathway links the family of names to the English place-name Riley, from Old English ryge + lēah, “rye clearing.” Because the spelling is rare, pronunciation varies; families often choose either RYE-lee or RYLE to match the better-known forms.

Born of the O’Reilly chiefs of Breifne (Cavan and Leitrim), the surname spread through the Irish diaspora and entered given-name use in the 19th century, becoming widely unisex in the late 20th. Reill appeals as a minimalist twist while preserving the lineage. Close variants include Reilly, Riley, Ryley, Reily, and Reille; cognate or parallel forms include Riel (French/Canadian) and Reil/Reihl (German).
