From the experts:
Morag is one of the quintessential Baby-Names">Scottish names for girls. Actually a diminutive of Mor, it has always been used more than the original. Commonly heard in Scotland, but could lead to pronunciation problems elsewhere, and the second syllable could prove very confusing. Morag is sometimes used as the Gaelic equivalent of Sarah. In the Harry Potter books, Morag MacDougal was a witch who attended Hogwarts in the same year as Harry.
