Renehan Name Meaning
Irish: shortened Anglicized form of Gaelic Ó Reannacháin ‘descendant of Reannachán’ from a diminutive of reannach ‘sharp-pointed’ or ‘starry’. The name is also occasionally translated into English as Ferns (see Fearn ) due to similarity with Irish raithneach ‘fern’. Compare McGranahan .
