Ancient ancestry testing uncovers your ancestral origins, taking you back to the very beginning of your ancestral lineage. It is not like traditional genealogy and does not provide information on tracing present day relatives. Rather, ancient ancestry goes back tens of thousands of years to your ancestral roots.
By identifying DNA markers using Y chromosome DNA testing, it is possible to discover where and when your ancient ancestors originated, and retrace their genetic footprints across the globe over thousands of years.
Note that the Y chromosome does not provide information about your mother's family nor any of the women who married into your fatherline. Only men carry a Y chromosome, so it is not possible for a woman to receive this test. Any woman who is interested in learning about her fatherline should have a direct male relative (for example, father or brother) take the test on her behalf.
