Mac Raghnaill Mac Raghnaill Mac Raghnaill is masculine surname in the Irish language. The name translates into English as "son of "Raghnall"". The surname originated as a patronym, however it no longer refers to the actual name of the bearer's father. The name "Raghnall" is a Gaelic derivative of the Old Norse personal name "Røgnvaldr" / "Rǫgnvaldr" / "Rögnvaldr". Variant forms of the surname include Mac Rághnaill and Mac Raonaill. These three surnames can be Anglicised variously as: "MacRannall", "MacRanald", "MacRandell", "MacCrindle", "MacReynold", "MacReynolds", "Randalson", "Rondalson", "Reynoldson", "Rannals", "Randals", "Randles", "Ranolds", and "Reynolds". The Irish surnames are borne by numerous unrelated families;

A 1998 book attributes the changes to the rules to computer informatics, and notes the Mac/Mc change as its first example. 1982's "Scottish Roots", a guide for family history researchers, warns that older Scottish records do not in fact follow this convention, unlike contemporary telephone directories. A 2001 book of "New York Times" theatre reviews sorts Mc names as if spelled Mac. A 2002 official document for the State of Vermont recommends explicitly no special treatment for Mac and Mc.
