Crickhollow:

The cottage that Frodo Baggins bought in Buckland after he sold Bag-End as a part of his plan to leave the Shire. Who he bought the house from is not said. Frodo only stayed there overnight the one night, before leaving again. A few days after the four hobbits left, the Black Riders discovered thre place and broke down the door.

Crickhollow is not mentioned again until after the War of the Ring, when it was named as the place that Meriadoc Brandybuck and Peregrin Took lived.
