Hi And welcome,I was searching the griffiths registrations and found a Michael Corcoran living in Castle st Dunmaway Fanlobbus Cork.

There is also a registration for a Daniel Kerrigan at Cat Lane Dunmaway fanlobbus cork.

At present the family records for this area are not on line,

Not sure what year John Joseph was born,Would say about 1880 same as Gladys.Birth records will be held by the GRO IRELAND.

 

If there is any other info you can give us it may help track them down,As i cant say for certain this is correct Michael,The two names in the same area make me think that this is a possible Match.

 

MIKE
