Walwan

Walwan is a rare Welsh name, a variant of Gwalchmai. The name Gwalchmai itself is ancient, appearing in early Welsh literature and mythology. It is most famously associated with Sir Gawain, one of the Knights of the Round Table in Arthurian legend. The name's components are thought to mean 'hawk of May' or 'hawk of battle', though the 'valley of the Welsh' interpretation is also proposed, particularly for the 'Walwan' form which may have been influenced by Germanic 'walh' (foreigner, Welshman) and 'wan' (valley or white).

The name's usage has been historically limited, primarily within Welsh-speaking regions. Its connection to Arthurian romance gives it a noble and chivalrous connotation, though it has never achieved widespread popularity outside of specific cultural contexts. The 'Walwan' spelling is less common than 'Gwalchmai' or 'Gawain', suggesting it might be a more localized or archaic variant.
