Royeaux

Could you clarify what Royeaux refers to? It could be a place, a surname, or something else, and I want to write a precise, neutral wiki-style article. If it is a place, please specify the country and any regional details (for example, province or department) and whether you want a historical or current-focused article. If it is a person or another subject, please provide the relevant context or context you’d like highlighted.
