When an address is not provided, the assumption is the person is from Clark County, Missouri. You will find some marriage listed twice, and this is probable because in the early years there was no time limit on filling the record of marriages. Some marriages were not reported to the recorder of deeds office for over a year, and some marriages were never reported. During the years I have index, a license was not issued. License was not required until the late 1800.
