Guise

The name Guise is a rare and archaic name with Germanic roots. It is believed to be derived from the Old High German element *gisil*, meaning 'pledge' or 'hostage'. This element was common in names like Gisbert and Gisulf. Over time, the name evolved and was adopted into various European languages, though it remained relatively uncommon.

Its usage is most notably associated with the powerful French noble family, the House of Guise, which played a significant role in French history, particularly during the Wars of Religion in the 16th century. While the family name is well-known, its use as a given name has always been extremely rare, often appearing as a surname first.
