Question: Are there any companies or individuals that one can hire to assist in researching a Jewish family's genealogy?
Answer: I would recommend checking the website: http://www.jewishgen.org. The website contains many helpful links and databases that can assist in tracing ancestry and roots. There are also discussion groups that you can join. The people who belong to the discussion groups will probably be able to assist you in choosing a company or individual who will be able to assist you with this research. http://www.avotaynu.com is another website that might be of assistance in these matters. At the following website I found a list of people and companies that specialize in researching Jewish genealogy: http://genealogypro.com/directories/Jewish.html.
