Hi, I found 4 children born to this couple:
Patrick - 1 May 1856 - Collon, Co. Louth - Roman Catholic
James - 24 May 1857 - Collon, Co. Louth - Roman Catholic
Thomas - 27 Feb 1859 - Slane, Co. Meath - Roman Catholic
John - 25 May 1862 - Collon, Co. Louth - Roman Catholic
The marriage was a little trickier, but I believe I have found it: John Reid? and Catherine McCabe married in Collon, Co. Louth on 1 Jan 1856. Checking the original page it looks like Reid should actually be Sheil. Unfortunately as is often the case with RC marriages the names of the parents of the bride and groom are not given in the records.
Hope this helps,
Michael.
