Gondor, Rohan and Lorien

[The Mouth of Sauron]

LOTR reveals that in both Gondor and Rohan there was very little knowledge of Lorien and even less trust .

Surely however, particularly in the case of Rohan, geography was against this ignorance and fear . The northern border of Rohan was the River Limlight , no more than 100-125 miles from Lorien . Surely over the 500 years of Rohan's existence before the War of the Ring contact would have been established ?

They were after all on the same side .

In some of Tolkien's writings Rohan has dealings with the Beornings, men in the Vale of Anduin and the Woodmen in Mirkwood so surely there must have been some dealings with Lorien .
