| Scottish, diminutive of Malcolm for which it is also considered to be the Gaelic equivalent. Calum/Callum is derived from the 6th century Irish Saint, Columba, from Latin "dove". Cailean may be Anglicized as either Callum/Calum or Colin. However these two Anglicized names are not interchageable so we have classed them as lesser synonyms. The Irish equivalents are Colm and Colum. |
