"Rory O'More" was a celebrated Irish rebel of the 16th century, and "Rory O'Moore" was another of the 17th.

Samuel Lover's 1837 bestseller "Rory O'More: A National Romance" was reprinted for decades and spread O'More's name far beyond Ireland.

The double jig called "Rory O'More" possibly comes from Lover's operatic version of the story, also published in 1837.
