Genealogy is a closely related field and genealogy studies sometimes rely on DNA testing. Ancestry testing can help you trace your ancestry based on genetic evidence. Your maternal ancestors, paternal ancestry and a general idea of the anthropological regions you ancestors came from can all be traced by testing your DNA. An mitochondrial DNA test can help connect you to you maternal lineage whilst Y chromosome test can help trace your paternity lineage.
Genealogy studies and genealogists study families and help trace their history and lineage. If you wish to know more about your family then you know where to begin. Tracing your family tree is beyond the scope of a DNA ancestry test as these tests will give you a more general view and take you back thousands of years. If you wish to begin your own genealogy study and draw your family tree, you might want to begin by having a peak, patiently; through the public registry- here you will find birth records, death records, marriage certificates and divorce certificates. In many cases, churches too hold valuable demographic records you might wish to go through.
Family tree research can also be done by accessing various genealogy sites which have a database of surnames. Once you insert your surname and geographical location and some other information, these websites will see if they can find and matches. Of course, these are rather in accruate and it is very hard to determine whether people sharing the same surname are actually related.
