Have you checked the marriage record of James and Eliza Jane in 1878?
It should list the father of each.

Is she Eliza Costain?

I see that the James Kelly ch 30 Apr 1851 s/o John & Anne was a patron submission
James ch 24 Nov 1852 Patrick was s/o John & Jane--parish extraction
There also was James ch 28 Mar 1852 Marown s/o James Kelly and Anne

Which of these was your source? Or something else?
