I have a Cadigan line from Cape Clear (my paternal grandmother's family). My family settled in Boston MA. I also have Sheehans--that I think are at least remotely connected--I also have Driscolls from Cape Clear that I think have a remote connection to my Cadigan line. Donahue is another connection. What I have learned of Cape Clear leads me to believe that they were all some degreee of cousin to each other--through intermarriage. i would love to learn what you have--see if a more definite connection can be made.
