Home research with or without digitalarkivet

I have been doing research (and detailed documentation) on my Norwegian ancestors. Fortunately, many came from Ringebu, where there are many good records going back to 1696 in the Digitalarkivet. I am not multi-lingual, but was impressed with the system once I learned how to access it. Now, I am going back further and into other parishes of Norway. I have a few questions on the interpretation of the Digitalarkivet information and where to go for more information: 1. In the Digitalarkivet marriages, there are two columns relating to dates. I have traveled in many countries, but are not equipped for accurate, detailed reading of other languages. The left column gives a "marriage date" and a column further to the right gives other information, often a date that is later than the first. I assume this is the marriage date and the other is the marriage contract date. - Is this correct? I assume the burial date and place is that and not the death location. 2. I have found a number of ancestors listed as "soldiers", "sargeants. etc.". Is there an on-line source for this military information or do I have to order microfilms or travel to a research source (I live in Minneapolis/St. Paul)? 3. A number of ancestors married people from Gausdal. Since there is little infromation (prior to 1800) on Gausdal in Digitalarkivet, are the films from SLC the most convenient? 4. There is a possibility that I also have ancestors (from another branch) from the Sel area. There is little easily available early (prior to 1800) information on this area also? Thank you for your assistance and opinions. - It is the only way to learn. Richard (Dick) Schumacher
