The first document is the marriage between August Heinrich Goeringer and Marie Juliane Constantie Matigue (I'm reading the letters as a -t- and -g- when compared to other letters on the page).
The second is the death record for Heinrich Eduard Goeringer, the informant being his wife, and here her maiden name is clearly spelled Malique. I think both men are the same, their birth year calculates out as 1811 and 1812 respectively. The difference in name may be resolved by finding the birth/baptismal record, there might be the additional Eduard on it. It may be the same as what you have for Juliane: German customs does not have middle names, all given names are equal and people are free to use as their common name whichever they choose. Marie Juliane Constantie obviously chose Juliane and her husband might at some point preferred August and later Eduard - or he might have gone by Heinrich and his wife didn't necessarily recall the second name.
For these reasons it is generally not a good idea for non-American or non-English people to use the Middle Name field, instead put all given names in the First Name field and the one they used most in the Preferred Name field.
