Rushey was a small village of the Marish, in the Eastfarthing of the Shire, spelt 'Rushy' on the map accompanying The Lord of the Rings.
The name means "Rush-isle". -ey or -y in English place-names has the sense "small island", as seen in Girdley.
It was called so as "a 'hard' among the fens of the Marish".
