Thanks to Family History Library (FHL) during the last decades  Salt Lake City, Utah, has developed as the world capital of genealogy research. Many organizations, centers, companies and individual researchers help with professional research in depth to find your ancestors in the USA and abroad.
     The beginning of research usually starts with data-base such as:
     International Genealogical Index (
IGI)
           
Ancestry.com
                         Ellis Island data-base of immigration records, or similar.

     
The core of the research however, are the millions of films in Family History Library which are available without any charges for everybody who would like to find his/her ancestors. But in many cases the searchers have troubles with their genealogy research. Below are listed useful links to some professionals who can help you to find your ancestors in the USA and in Europe:
