Genealogy may seem like it is easy, but it is a complex field that involves intense research and knowledge of documentation, as well as history. There are several things to remember when you are looking to start building a family tree.

1. Be careful of people with common names in big cities.

If you find people who have very common last names (and/or first names) and lived in big American cities such as Chicago or New York as immigrants, be careful to get more information about the family. Any other unique information, such as children's names and ages, occupations and even street addresses can help narrow down a search to find the correct family. 

2. Remember that the people who submit the information for a vital record are not always correct

When someone dies, their next of kin will usually supply the information for a death certificate. Even though it is an official document, it does not mean everything is necessarily true, it is only the amount of information that the next of kin may remember or have been told at the time.

Dates and places on various documents can sometimes contradict each other, and this can happen if different people supplied or recorded the information.

Keep in mind that names can be misspelled, or in many cases deliberately changed by a family in order to assimilate into a new culture. 

3. Use your local library!

Local libraries often have genealogy groups or clubs that meet regularly, with experts who have access to paid online resources. Look up local libraries in your area or email your local librarian if you get stuck and need some research help.
