Good afternoon I am again hoping to receive some advice or assistance. I am compiling histories of people who have resided in Blacktown City though not restricting their biographies to certain years. I am having difficulty locating excat dates that the districts received their official names in Blacktown City. I have checked "The Geographical Names Board" to come up against a brick wall. I am aware of when the Housing Estate at Mount Druitt named their Districts but it is the other areas I require. Any help would be most appreciated. Warm Regards Hazel E. Magann.
