Celtic names are derived from the languages and cultures of the Celtic peoples, primarily found in regions like Ireland, Scotland, Wales, and Brittany. These names often have meanings related to nature, history, or personal traits, reflecting the rich heritage of the Celtic tradition. Common elements in Celtic names include prefixes like "Mac" (meaning son) and "O'" (meaning descendant of), which indicate lineage. Many Celtic names have variations in spelling and pronunciation across different regions. For example, the name Siobhan in Irish translates to Joan in English. These names are not only significant in personal identity but also play a role in preserving the cultural history of the Celtic peoples.
