Combination of Old English 'ead' (wealth/fortune) with May, meaning 'prosperous in May.'
Edmay combines the Old English element ead, meaning wealth or fortune, with May, the name of the spring month and flower. That fusion gives it a pleasant double resonance: prosperity on one side, seasonal freshness on the other.
Edmay feels compact, gentle, and slightly old-fashioned in a way that can seem charming rather than dated. It belongs to the long tradition of names built from meaningful fragments, where language itself supplies both blessing and imagery. The result is a name with a quiet brightness and a naturally hopeful tone.
