All the variations for Kane appear to be derived from O'Cahan and Cahan. These names were common in early documents for Northern Antrim 1500's and early 1600's .
In searching the records I have what seems to be an interesting phenomenon.
Following the O'Niell rebellion of the 1640's and the subsequent intervention by Oliver Cromwell the members of this family seem to have left Northern Antrim for close to 100 years.
There are no Variations for the name in the 1669 Hearth money Rolls for Billy Parish or Balintoy , nor are there any in the 1740 Protestant Householders, or the 1734 Religious census for Cary, I have both the Billy Parish and the Ballintoy names for that census.
Then in the 1766 census for Balintoy there are several Kanes and with the 1803 Agricultural Census and the 1826 Tithe records there are numerous members of the family back in Northern Antrim.
It would seem that the members of this family must have taken refuge in other parts of Ulster, from the mid 1600's, and then after about 1750 the descendants of these families are returning to what I would regard as their cultural heartland, Northern Antrim.
