I have records for this family-
14 Feb.1827 Jane Gordon, dau. of Joseph & Ellen of Ballywilliam
28 Sept.1838 Nancy Gordon, dau. of Joseph & Ellen of Ballywilliam
Jane Gordon (died 1868) married 1855 Samuel Conway of Cah & had at least 4 sons (Hugh, Joseph, John, William).
Nancy Gordon married 1865 Joseph Taylor & had Joseph, John, Joseph, Margaret Jane.
Joseph Gordon & Ellen also had a son James who died at Cah in 1882 and a few months later Allan Conway of Cah applied to put James' daughter Margaret "of weak mind" into Coleraine Workhouse.
Now, strangely enough, although Nathaniel wasn't a terribly common Christian name in the area, Allan Conway of Cah named a son Nathaniel and Nathaniel had a daughter Elizabeth Gordon Conway. Allan Conway's wife was called Elizabeth & I'm checking my notes to see if there's any chance his wife could have been Elizabeth Gordon.
Added- James Gordon's death registered by brother-in-law Allan Conway so it looks as though Allan's wife was Elizabeth Gordon
