Other way around I reckon. MacDonald, Mackay, Macleod etc. Though I daresay if you trace the etymology they'll probably be interchangeable....
You may be right, though I've not seen a 'MacDonald',; only a Macdonald'. I rather think that those northern Irish, who originally came across from Scotland, probably allowed their original 'Mc's to migrate to other forms.
