Durham Records Office

Following an everyday Google search I stumbled upon some documents from Clayton & Gibson (solicitors) held by Durham Records Office.   That below outlines & refers to the agreement of the Grand Allies underlying establishment & use of the Tanfield Waggonway:

Ref: D/CG 16/1078

There are many references to our history at the Durham Records Office.   By chance I ended up at  http://www.durhamrecordoffice.org.uk/article/11111?SearchType=Param&Variations=Y&Keywords=baptist&ImagesOnly=N&ItemID=165304

then used Windows search CTRL-F & entered a term of interest, eg Tanfield, Bowes, Brandling, coal, etc to bring notes on historical documents into focus.   For sight of the actual documents, we'll have to wait until Durham Records Office is accessible.

Searching for wayleave yields, for example:
Ref: D/CG 16/1129

George, Earl of Ravensworth (2) James Joicey of Dissington Hall, Northumberland, coal owner and William James Joicey of Urpeth Lodge, Durham, coal owner, trading as James Joicey and Company Draft lease by (1) to (2) of a wayleave over the Tanfield Branch of the North Eastern Railway for 21 years from 1 November 1879 Rent: £300 p.a.

Searching for Marley gives:
