It is the marriage "application" you want.A couple fills out the "application" with their personal information.They receive a "license" to get married.After they are married they will receive a "certificate" to show they are married.The certificate won't give all that personal information.
Now, records vary over time, so I cannot say what you may find on the application.In very early times mostly the only record you will find is a type of marriage "registry."Names of groom and bride, date of license and date of marriage (some times a few days apart), name of who performed the marriage, and if one or both are underage, names of those who gave permission for them to marry.
Difference in date of license and date of marriage sometimes the reason you will see researchers with slightly different dates for a marriage.Example, many people show the wrong date for the marriage of James Rambo and Winie Adams in 1835, because they took the day in the first column on the registry.That day is when they obtained their license, they were married later.
I just jump in and try to help others when I think I can.By the way, sometimes it takes a few minutes for your resoponse to show up, but after you click on "Post Message" and it says message posted, it will be there.
