Two truths and a lie...

[Pitchwife]

1. According to LotR, Prologue:

The habit of building farmhouses and barns was said to have begun among the inhabitants of the Marish down by the Brandywine. The Hobbits of that quarter, the Eastfarthing, were rather large and heavy-legged, and they wore dwarf-boots in muddy weather. But they were well known to be Stoors in a large part of their blood [...]

2. LotR V,3, The Muster of Rohan:

east and onward rode the Eorlingas
through Folde and Fenmarch and the Firienwood

and:

And then on again through the Folde; and through the Fenmarch[...]

3. According to the Shire map, Rushock Bog was located along the Water (where it divides into two arms, north-west of Hobbiton).

So 2 is obviously untrue!
