Looking for O Neil L of Molong Nsw

Looking for further information on Sarah Murray who married John Joseph O'Neil on 28 February 1878 at Kirk Connell, NSW (Kirkconnell). Trying to find their parents. I know that they had a son "Michael - elder born of twins" on 5 October 1882 at Edinburgh, NSW. Where is Edinburgh? Is it a property name - as it does not exist as a town.
