Paul,
Blackhill was in the Registration District of Lanchester and I think that is the reason why many born in North West Durham simply entered their place of birth as Lanchester which in the case of your Shannon family was incorrect seeing the first four children were not even born in the Lanchester District. According to the 1861 census when the family are to be found at Tow Law, the first two children Edward and Isabel were born at Wallsend whilst your great-grandfather Thomas was born at Newcastle and Sarah was born Tow Law, the family then returned to Blackhill where the rest of the children born. By todays standards living conditions no doubt were harsh but people did have their dignity. Anecdotal evidence I have collected suggests that many families kept their houses spotlessly clean and in the case of your Shannon ancestors Bottle Bank, Blackhill appears to have been a worthy place to return to for the rest of their lives after living at Wallsend, Newcastle and Tow Law.
Let us know who John Kelly's father was when the marriage certificate arrives, also, if given, John's age.
Good Luck,
J.T.A.
