Our Corrins originated as farmers in Arbory in the late 1500's and many moved to Castletown the closest town. I would think that there's a 50% chance there could be a connection. Have to go back to about 1880 if you can with the names, birth dates. I have the 1881 census for Malew including Castletown and there were 6 Corrin families living there at that time and 3 are my relatives. You can contact me direct if you wish.
