There may be several dates associated with a "marriage." There may be a date of the license, the date of a bond, the date the license was returned, the date the license was recorded, and the date of the marriage.
Not all locations have all these records, but make the distinction between them so that you are clear. Getting the bond or getting the license does not guarantee that there was a marriage---just that there was an impending marriage. Things can happen to cause a marriage not to take place.
