Not to go off topic, but you bring up a good point. We actually have two sets of founding fathers, with some overlap. The group that fought for our independence against Britain and the group that wrote the constitution.

OIFVeteran: "We actually have two sets of founding fathers, with some overlap.
The group that fought for our independence against Britain and the group that wrote the constitution."

This listing of Founders shows only Roger Sherman as present in all four Founding events -- 1774 Continental Congress, 1776 Declaration of Independence, 1777 Articles of Confederation and 1787 Constitution Convention.
George Washington was present in the beginning and at the end, but missed out on the Declaration & Articles of Confederation -- he was, ahem, busy elsewhere.

Of those who signed the Declaration, six also signed the Constitution.
But the largest figures -- Franklin, Washington, Adams & Jefferson -- were active throughout, from 1774 to 1788.

On the issue of slavery, in 1776 all opposed it in theory, but in practice, not so many.
By 1787 still all opposed slavery in theory, and already many also opposed it in practice, even Southerners like Washington & Jefferson.
