Hi Diane,
I will try to help you, Clarkes are very plentiful, in this area & I was wondering did you have a townland that they may have come from. On the other hand Curran is not as common & I have seen Curran on the headstones in Moybologue Graveyard, which is about 4 or 5 mile from Bailieborough on the Meath border.
If James Joseph Clarke was born in 1863, you should be able to get his Baptism records, Civil Registeration started in 1864 & if any of his siblings were born after that, I would concentrate on them.
When did or did James Joseph emigrate?
There are 13 James Clarkes in 1901 Census, you can see them here & there may be more, if any variant spellings are looked at

Civil registration records are available from the General Register Office (GRO). These start from 1864. You can access the website here:http://www.groireland.ie/research.htm Or you might try Valuations office in Dublin (http://www.valoff.ie) which will have a record of the land registry from 1855 to modern times. This will assist in seeing what happened to any land the familymay have owned (as it usually passed on to a relation).
You could also try contacting the Cavan Co Library for further assistance.
