<Has anyone ever heard of the name Wigdor?>

Pronounced Vigdor, it is a given name that is a variation on Avigdor, which
in turn is derived >from the biblical expression Avi Gedor, father of Gedor,
which is found in 1 Chronicles 4:4. & 4:18.

For reasons that are not at all clear, this was a nickname for Moses.
