What appears in marriage registers is very variable and can be inconsistent within the same register. At this period a register usually gives the couple's names and the date they indicated their intention to marry. It usually mentions if one of them was from a different parish. Other information is a bonus. Some session clerks recorded when the banns were read, and some added the fact that the couple had married and when. If you know that the couple were married, then any difference from other entries of the page may just be due to the clerk's poor memory or the notes he is copying from not being clear enough.
