Rollo Boffin told you of Odo Burrow, Longo's father. He had a farmstead in the south, but Longo abandoned it when his father died. Rollo is curious if Longo is using it again for some other purpose.
'If I were to guess where that southbound trail of leaf goes, I would say it winds up at old Odo's leaf-barn. Odo Burrow was Longo's father, and he was everything Longo isn't, meaning he was a fine, respectable hobbit. When old Odo died, Longo inherited everything, including that farmstead to the south of here. Longo abandoned it, but I wonder if he isn't still using it for something.
'If you travel south from the Wellbridge, west of Woodhall, you'll come across the farmstead. If you search the crates and boxes out there, you might find some clue to your missing Took.
'I have a feeling this might be dangerous, ${PLAYER}. You should bring some friends if you plan on going to that farmhouse.'
Odo Burrow's old leaf-farm is south of the clearing where you found the missing waggon.
When you found Longo's missing waggon, there was no sign of Gerebert Took, but the leaf had been moved southwards. Rollo Boffin suggested you search boxes and crates at Odo Burrow's old farm for some sign of Gerebert. He warned you to bring friends, for it might be dangerous.
Esilia Took can be found near the centre of Tuckborough.
At old Odo's leaf-barn, you stumbled across Gerebert Took. Once you freed him, you were attacked by some strange Men. After defending Gerebert from the Men who attacked you, he escaped and said he would meet you back at Esilia Took's house.
