Under “Websites” I posted a link to all the United States Census Headings. Many people emigrated from Denmark to the United States especially in the late 1800’s. One way that I have been able to track people in the United States when I have the Danish birth date is by looking at World War 1 Enlistment for men. Social Security Death Records have also been helpful. Remember people don’t typically put specific parish places of birth. It will be something like Copenhagen instead of Vor Frue Kirke.
