How were Adams and Jackson's backgrounds different, and how did they compare to those of earlier presidents?

Jackson was not rich, not from one of the old , established American families. He had had little education and had no connection with the founding fathers, who fomented the American revolution, conducted the Revolutionary War and wrote and ratified the US Constitution. All of the presidents before him were "in on the ground floor", so to speak, either founding fathers or in the case of Quincy Adams, the son of a founding father, and so all had ties and position in the administration that came before them. Jackson's parents were poor immigrants and he lived in the Western frontier rather than on the seaboard.

Unlike the first six presidents, Jackson was the son of immigrants , had no connection to the any of the founding fathers and lived on the Western frontier rather than in Massachusetts or Virginia.
