3rd Presbyterian Church records, Antrim County.

Is there a volunteer who would be willing and is able to look up 3rd Presbyterian church records for me? I am a senior citizen living in Canada and don't have the finances to visit Ireland.  I am looking for the parents of Hugh Cooper and Margaret Jane Thompson. They were married on the 11 July 1878 in Ballymoney, Antrim Co. in the 3rd Presbyterian Church.   Hugh's place of residence is  Carnaff and Margaret's is Eden. On the marriage certificate Hugh's father is John Cooper and Margarets is Moses Thompson.  One of the witnesses is named Hannah Cooper. On Hugh's death record (7 May 1908, Balnamore)he has the  middle name of Caldwell. I am hoping for any record-Birth, baptism, etc. for either or both parents and maybe siblings also of Hugh amd Margaret.  I know records for the early years aren't that great but  anything will  help.  Thank you    Sheila.
