You've put your own WikiTree profile rather than Maria's so just for convenience it's https://www.wikitree.com/wiki/Becker-7851
Her baptism record and marriage record both have identical birthdates of 14 March 1807 so I would take that over the current profile date of 1811.

From google maps I see that Kirchen, Altenkirchen and Herdorf, Altenkirchen are neighbouring towns so Niederklein seems highly unlikely. Although there are four sources for the marriage, three of them give the same date so I'd just use that. As Abm says, we can't see the images so can't fully investigate but this supposed Niederklein marriage just seems like a mistake.
Edit: I see the profile has a birth in Niederklein too so it looks as if the wrong person's data has been used.
