There was a Whig party in early America of course, not too sure about the Presbyterian impact — but then, leave it to the hidebound Brits to get it wrong.

Not so much the formal Whig U.S. party. The English of that time would regard any republicans as Whigs as in the sense the Tories regarded anyone who supported the Cromwellian republic or their descendants as Whigs.

The English of that day would regard anyone whose church was not governed by bishops as Presbyterians, so that would include New England congregationalists. It did not include baptists or Quakers, however.
