You could, however, choose an Irish name with a similar meaning or sound:
* Líne: This is probably the closest phonetically. It means "line." While not a direct translation, it's a reasonably close approximation of the sound.
Ultimately, the best choice depends on personal preference. If a precise translation isn't needed, *Líne* is a good option; if a meaningful Irish name is preferred, consider researching Irish names with meanings you find resonate with the essence of "Linda."
