Looking into Mr. James Whitely for you: Perhaps you already saw this from the Internet. I tried to find a record of the Baptism of James and in doing so came accross the record of a Martin Whitly baptised in the same parish (Paulstown) in 1845. I could find nothing when I changed the surname of James to Whitly. You have a lot of info on his family in Australia. Ancestry.com may have info that would lead back to something in Ireland.
Sorry I cannot be of further assistance. If I find anything further I will get back to you.
