Re: O'NEILLS OF PORTMARNOCK IRELAND
Co. Wexford is in the sunny south-east of Ireland.Dublin is on the east coast.Depending on where in Wexford your O'Neills are from the distance is approx. 70 - 80 miles.
I am researching my O'Neill ancestors from Co. Kildare which is about 30 miles from Portmarnock however I haven't come across any of my ancestors living in that area of Dublin.
Best of luck,
