Genealogy research for Denmark is easier than in many other countries, because their records are stored at a country level. Since their census and vital records are catalogued by country, district and parish, it’s easier to find your ancestors if you know where they live, but at least you have access to all counties through the same source. Most parish records have been scanned and catalogued and many have been transcribed.
Google translate can come in handy if you do not know Danish. I’ve included the link below also.
