While the name of Staines does indeed mean stones we at Spelthorne Museum (colleagues of Christine Lake who wrote Up Pontes) now favour the idea that the stones referred to indicated the gravelled Roman Road that ran through Staines leading to the Roman bridging point rather than the Negen Stones. Names such as "Stane Street" have obvious connections with Roman Roads.
However, we haven't given up on the Negen Stones.....
Something is not right. This message is just to keep things from messing up down the road
