I'm new at the DNA testing but here are my results. After receiving my DNA results in January 2016 my first match was with a known cousin who is also on Ancestry with a score of 959 centimorgans at 41 segments. That's all the information from the site but I thought this looks very reliable since she is a known first cousin.
My second match came a day later with a male individual with a shared score of 1775 centimorgans at 46 segments and the predicted relationship is HALF SIBLING. Since they are adopted this would make him my half brother, same father but different mothers.
When I consulted and asked Ancestry DNA about the results they said their test was very reliable with those high scores. Another option they suggested was to take a relationship test but half brother testing still may or may not be confirmed with this test and show the same result. The documentation is limited and there is only hear-say information about the possible relationship between the couple.
Should I take these results as reliable or does anyone recommend a test that would be more conclusive? There are no parents still living.
If I can rule out everything except half-brother would you still recommend either GEDMatch or FTDNA? If yes, which would be better?
