How did the Founding Fathers feel about Traditional Marriage?

It is hard to be certain of their exact feelings. The official documents they produced, the Constitution, the Articles of Confederation, and the Declaration of Independence, for example, do not ever mention "marriage", "husband", "wife", or "family".

In their personal lives, some had very traditional marriages and were quite conservative about such things; John Adams is one example. Others were flamboyant in their disregard for marriage; Benjamin Franklin had a wife at home while maintaining a live-in relationship while he was Ambassador to France for several years. Others had arrangements that were maintained outside public view; Thomas Jefferson had a lengthy relationship with a woman who was legally his slave. There does not seem to be anything like unanimity on the concept of marriage, and more than likely most of them would have thought it was not the business of the government.
