Looking for a list of the most inspiring or distinctive Celtic baby names for your newborn boy?

Renewed interest in the Celtic languages has led to a wider reverence for Celtic traditions, culture, and practice, and an increased focus on the need to preserve the Celtic languages - of which Welsh, Scottish, Irish, Gaelic, Cornish, and Breton are a part.
