Resolute protector
A rare spelling variant of the classic Germanic name William. It is derived from the elements 'wil', meaning desire or will, and 'helm', meaning helmet or protection. This specific three-'l' spelling is highly unusual and likely a modern creative variation or a typographical variant of the traditional form.
