Mohan surname: questions
What does the surname Mohan mean?
Woulfe gives Mohan as a form of Ó Mocháin, 'descendant of Mochán', which he explains as a 'pet' form of some name beginning with moch-, 'early'.[1]
Are Mohan and Mahon the same name?
Sometimes. Woulfe lists both Mohan and Mahon among the anglicised forms of Ó Mocháin, and says the Galway family generally anglicise it Mahon. Matheson's list of spelling varieties gives [Mahon] under Mohan. Woulfe also gives Mahon among the forms of two other names, Ó Mathghamhna and Mac Mathghamhna.[1][4][10][11]
Where in Ireland is the Mohan name from?
Woulfe names a Cinel Ianna family in Co. Galway and an ecclesiastical family at Killaraght, Co. Sligo, and says Ó Mocháin is 'now a fairly common surname all through the South of Ireland, as well as in Connacht'. In 1890, Mohan births were found principally in Monaghan.[1][3]
Is Vaughan an Irish form of Mohan?
Woulfe says that in Munster Ó Mocháin is 'generally anglicised Vaughan', a form evidently derived from the genitive case Uí Mhocháin.[1]
