I have a copy of the Henry County Alabama Records Marriage Book. In the front of the book the author states that in Marriage Book , 1821 - 1868 the marriage records from this volume have previously been extracted and printed. Unfortunately , the first printed versions of the marriages incorrectly recorded the license dates as the marriage dates. Unless your ancestor was married on the same day they bought the license. The dates of marriage, previously published by other authors , is incorrect. Hope this helps.
