Molly I
From Tardis Wiki, the free Doctor Who reference
Molly I and George I were the first Burden beasts to serve the Robinsons.
During a storm both beasts were left outside the Homestead and perished. Their remains were later served at a gathering for the people of Our Town. When Lora Robinson required the assistance of two more burden beasts she named them Molly II and George II in memory of the originals. (PROSE: Lost on Mars) When viewing the Ancients' equiptment, Lora realised that she was viewing past events as she saw her original two burden beasts alive and well. (PROSE: The Heart of Mars)
