The information I have found on this tree is as follows, hope it helps.
Charles McCurley(b1806) was married to Bridget McNulty(B 1808)
They had 4 children Margaret, Hugh, Charles and William(my direct relation)
Charles married Sarah O'Kane
William Married Ellen Mann(Glenravel Roman Catholic Church, Co. Antrim, Ireland)
As far as I can see Charles only had a son Hugh
William had 8 Children: Mary, William, Charles, Hugh, Patrick, John, James & Margaret
I can't find anything further back than Charles and Bridget.
