1) I will not look up a citation. If you don't know basic history then you need to get a book and learn.
2) tekbarrier, that's an ignorant comment. The whole point of the meme is that simply saying GW owned slaves gives the absolute wrong impression. Of course he owned slaves. He purchased many slaves, both to work the land, and to preserve families. And he worked his entire life to free as many as possible. He saw them as people in a time when slavery just WAS. Saying he owned slaves paints him as a hypocrite, which is the opposite of the truth.
