There are many places to find out about your ethnic roots. Some are more reliable than others. Before you go off searching in what you think is the "old country," be sure you have documented everything there is to know about your ancestors in this side of the pond. Several ethnic groups have a more difficult time with researching ancestors than others. Native Americans and slave descendants have a harder time than most. (We will cover these in more detail later on) Those of Jewish decent may have a hard time documenting individuals who did not leave Europe prior to 1939 (the onset of WWII). Again, there are ways to find out about this, you just have to know where to look.
