Stan, Havannah was a place in Washington Co Durham (where I was born and still live). There used to be an army camp there many years ago. After Washington changed to a New Town some of the place names changed too and Havannah was one of them. There's a large B&Q store in Blackfell now where Havannah used to be. If you want more information about it please let me know as my dad is a mine of information about Washington having been here for the last 80 years. Hope this is of some use to you Patricia
