Crellin Family History
Crellin Name Meaning
Manx: shortened form of Gaelic Mac Nialláin ‘son of Niallán’ a diminutive of the personal name Níall; see Neil . This name has been explained as a metathesized form of Crennall an Anglicized form of Gaelic Mac Raghnaill ‘son of Raghnall’ (a personal name from Old Norse Rǫgvaldr meaning ‘ruler of the gods’); this explanation however is doubtful.
