“I once counted them up. In 1776 all Southern and half of the Northern Founders were slaveholders.”

That is an interesting comment.

In your counting, was Delaware considered to be a northern or southern state?

And Pennsylvania? Was it counted as a northern state in your totals?

Delaware was a Southern state, though one of the two non-slaveholding Southern delegates in 1787 was a Quaker living in Delaware.

Pennsylvania was a Northern state and one of the first to begin abolition, in 1780.
