Mossie Donegan

From Memory Alpha, the free Star Trek reference

Mossie Donegan was an inhabitant of the holographic 19th century Irish village Fair Haven.

He had a talking pig, which he once brought over to Sullivan's. Katie O'Clare later claimed, her uncle and aunt owned a goat which could talk Donegan's pig under the table. (VOY: "Fair Haven", VOY: "Spirit Folk")
