Welcome to the Ministry of Magic’s Division of Ancestral Research (DoAR). The DoAR, founded in 1797, focuses on researching the different bloodlines and ancestry of magical humans, and works to reduce stigma against non-purebloods and promote equality in all magical folk.
The DoAR’s funding and efforts have increased significantly since 1998 and the Second Wizarding War, when any status other than pure-blood was persecuted by Voldemort and his followers.
You have found the DoAR’s website, which produces an “Error 404” message if accidentally stumbled upon by a Muggle in order to enforce the International Statute of Wizarding Secrecy.
