Denis, If you click on the link in Charlotte's answer, it will take you to the page where you can enter the information about the DNA test you took at Ancestry.com. After about 1 day your test information will automatically be displayed on your family members' profiles on WikiTree. If you decide to upload your Ancestry test to GEDmatch, GEDmatch will give you an ID that can be added to the information you've entered on WikiTree for your Ancestry test. On GEDmatch, if you select the One-to-Many matches option, GEDmatch will display people with whom you share DNA. That may help you in your search for your mother's paternal line.
