It was the name of a grain goddess; therefore, the meaning of the name also stands for grains. Grainne is the Gaelic version of Grania. The only little drawback of the name is that many other names sound very similar and are much known, so people assume it to be the other name. But because the name is super grounded, meaningful, and essential, one little drawback is excused. At the same time, it's not famous in countries like the USA, Australia, or other English countries. However, it's pretty well known in Irish Culture, and some very well-known personalities with the same name like Grainne Murphy, Grainne Kierans, Grainne Mary Clancy, and many more.
