Meaning:Will helmet; Resolute protector
Wilhelmus is a boy's name derived from the Old High German name Willahelm, meaning "will helmet." Another more rounded whole meaning is "resolute protector." Wilhelmus is a variant of the wildly popular names Wilhelm in German, Guillaume in French, and William in English. The Old Norman name Williame has also been credited with helping to spawn its popularity. Baby Wilhelmus can take inspiration from this stately name to always look out for those around them.
