Who is Solomon's first owner?

William Ford is Solomon's first owner. Solomon writes that Ford was kind to his slaves and was a moral Christian minister who could not be blamed for his views on slavery since it was the way he was raised. Solomon gains Ford's favor over and over again, and Ford comes to his defense in his troubles with Tibeats. Unfortunately, Ford has money troubles and has to sell Solomon.

The first owner is Burch, no ?

Burch was a slave trader, he took control of Solomon and transported him South in order to sell him, after Solomon was drugged by Brown and Hamilton.

I thought Burch was considered an owner, like Solomon was his, at first.
