Radigan

1. Irish (Connacht): variant of Ratigan.

2. Perhaps an altered spelling of the southern French family name Radigon, a diminutive of Radigue, which is of uncertain origin. It is largely confined to Gascony and is perhaps a derivative of Occitan razigar ‘to tear out or uproot’ (Latin eradicare, from radix, genitive radicis); if so, it is presumably a topographic name for someone who lived on a patch of cleared land.
