Let's get out facts straight. State issued marriage licenses in the U.S. date back much father than than 1929. Would you like to see the "Certified Copy of Marraige Record" issued in 1841 by the State of Ohio to one of my ancestors? Or the "Certificate of Marriage" from the same state to another in 1880? (the example shown below is not from my family)
In fact, State involvement in marriage goes all the way back to the 1600s in colonial America.

That isn’t what I heard lately, but say that is true, do you want the state granting you the right to get married as a conservative? Do you need that?
