As part of Good Morning America 's special family tree series, you can try Ancestry.com free for three days. In the process you can also register to win a vacation to your ancestral homeland, but you'll have to enter your family tree into My Ancestry. You can, however, still take advantage of the three free days by skipping this step. No credit card or other financial information is required. If you want to check out the rest of the GMA Family Tree series, it continues on November 2nd and 3rd on ABC.
