The possibilities for research are quite diverse and they depend on the request made. To give you an idea:

• Genealogical research into a family or person. You can think about that missing link or a breakthrough in your research that has stranded.
• Heraldic research. Does your family have a coat of arms?
• Historical research into a region, a house, a certain group of professions or the background or origin of a name.
• The making of a familybook

The best thing is of course to turn the result into a publication. That can be a book with a clear and attractive lay-out brought to life by documents and pictures. Depending on your wishes an article or a publication on the internet is possible too.
