If you are interested in finding your Danish ancestors with a minimum of external support, here is a DIY kit for starters:
A must read is this site:http://www.sa.dk/content/us/genealogy
Includes links to the
Census registers http://www.sa.dk/content/dk/ao-forside/find_folketallinger
Parish registers http://www.sa.dk/content/dk/ao-forside/find_kirkeboger
and the Danish Demographic Database (DDD) http://www.ddd.dda.dk/ddd_en.htm
More detailed background info is found here:https://www.familysearch.org/learn/wiki/en/Denmarkhttp://net.lib.byu.edu/fslab/researchoutlines/Scandinavia/De...
Note: A few of the references in this last document are outdated.
Placenames and Parishes:
Looking for placenames you can actually find a lot yourself. Give it a chance.
A. Outline map with counties and parishes.http://www.dis-danmark.dk/kort/kort.htm
B. Place name and parish database.http://www.krabsen.dk/stednavnebase/index.php
C. Very usefull list of churches/parishes with parish boundaries and detailed mapshttp://www.korttilkirken.dk/alfabetisk.htm
1. Find the church (alphabetical listing of churches – usually the Lutheran church and the parish name will be nearly identical) and click on the name. A new page opens for that church/parish.
2. Pick the menue item “sognegraensen” (not “kort” !) and you’ll see the parish on a zoomable, detailed map.
Eventually historical parcel maps may be available for the parish you picked. If this is the case, a menue item “Historiske Matrikelkort” is visible.
D. You may also search for historical maps directly from this page:http://www.korttilkirken.dk/herreder/AlfbHerred.htm
But that requires the name of the “Herred”. You’ll find that if you have picked a church/parish through C.1.
The parcel maps found here may be useful if a census record contains a parcel number for a household.
