Aunt Adah

From Memory Alpha, the free Star Trek reference.

Aunt Adah was the Human form assumed by the Caretaker to make the crew of USS Voyager feel at ease when the ship was transported to the Delta Quadrant in 2371.

She was a sweet elderly woman who lived on a farm and offered the crew lemonade and corn from her farm house. The figure turned violent when the crew discovered that all they were seeing was an illusion. (VOY: "Caretaker")

"Aunt Adah" was played by actress Angela Paton.
