I am interested in the name Greenough. Let me explain that I am BRICK collector, especially of locally made ones. I live in Towcester and my Grandfather was a Railway Bricklayer. I have over 225 differently named bricks in my collection, I contribute to a website that lists nearly 5,000 bricks from all over the UK. When I found a brick at a local reclamation yard with GREENOUGH in the frog, I started to research it. Thanks to this website and others I have found that he owned a steam operated brickworks in Kingsthorpe Road, Northampton, in joint ownership with Henry Martin. If you would like a photo of the brick or any other information about the works, let me know.
