Hi person with no name,
The original church records and several of the censuses can be found at http://www.sa.dk/ao/
Just click on In English on the left side for directions. When you call up the records it will give a column with opslag on the left. opslag means image number and helps others locate the record. Records can be found using the parish, herred, and amt. For instance, Jens Christian Gerner Jensen's birth and baptism in 1923will be found in the records for Aarhus Vor Frue, Hasle, Aarhus, opslag 43 number 29. On the top you will see F(births), K (confirmations), V (marriages), D (deaths), J (registers), A (persons leaving the parish), and T (persons coming into the parish).
Now for what I have found.
