Slatterys in Ballysheen

I have found Kerry RC Church records that indicate there was an Honora Slattery born in 1837 in Ballysheen to Daniel Slattery and Margaret Hanlon.  And a John Slattery was born in 1840 to the same couple.  I believe that they could be siblings of my g-grandfather Dennis, who was possibly born c. 1835 (records in Abbeydorney don't go back that far).  I don't know whether or not they stayed in Ireland, but if so, I would love to be able to find their descendants.  Also, I would like to get more information on Margaret Hanlon and Daniel Slattery.
