Gillermo is a masculine name that takes its inspiration from Guillermo, the Spanish form of William. Despite its overwhelming popularity and affiliation with Britain, William actually originated in Germany and was derived from Wilhelm. The roots of the name, wil, meaning "will" and "desire," and helm, meaning "helmet" and "protection," create baby Gillermo's Marvel-esque tagline of "resolute protector."
