The two words, curator and deliberatus, are Latin for guardian and determination, respectively.  When combined, determined guardian, it becomes the meaning of the name William.  William, in German, means strong protector, or in another variation, determined guardian.

According to the web site, Behind the Name, the origin of the name William comes from the Germanic name Willahelm meaning "will helmet", composed of the elements wil "will, desire" and helm "helmet, protection". Saint William of Gellone was an 8th-century cousin of Charlemagne who became a monk. The name was common among the Normans, and it became extremely popular in England after William the Conqueror was recognized as the first Norman king of England in the 11th century. From then until the modern era it has been among the most common of English names (with John, Thomas and Robert).

Thus,in  the meaning behind the name of William, determination or will, and protector or guadian, and then translated into Latin, becomes the name behind this web site: curatordeliberatus!
