Trivial Trivia - taking trivia to new levels

[RJNorton]

This is really trivial, but I will post it and see if anyone tries to find it. No restrictions on research.

One time an ox recently purchased by Thomas Lincoln broke out and wandered off. Thomas sent Abraham to bring the ox back. Abraham found the ox and decided to try to ride it home. After a lot of kicking and coaxing and attempts to buck him, Abraham determinedly rode the ox back home.

What was the ox's name?
