Bannerton Family History
Bannerton Surname Meaning
Of uncertain origin; possibly a variant of Bannatyne although De Bhulbh says the distribution of this spelling in Ballinasloe and Galway is very different from that of Bannatyne which is found in Belfast and Down.
Bannatyne is believed to have been brought from Arran and Bute.
However, respelling of names from Britain is quite common in Ireland.
