Hi MargM, Gwen & Listers, I believe that the original stone Christ Church, East Gosford was erected by Robert Creighton. [Source of information: Geoff Potter, Local Studies Librarian, Gosford City Library]. Robert Creighton arrived in the Colony of NSW in 1842 from Ireland, with his wife and four children, William, Elizabeth, Margaret and Robert. I am descended from his eldest son, William Creighton. I don't know when the original church was built. Best wishes Wendy McKenzie
