The
family name associated with the Counts of Atouguia was
Ataíde. The origin of the Ataídes can be traced documentally to Egas Duer, a 12th century
County of Portugal nobleman, likely a member of the medieval House of Ribadouro, whose son Martim Viegas was the 1st Lord of the
Honra and Torre de Ataíde, near present-day
Amarante in Northern Portugal. Martim Viegas' grandson, Gonçalo Viegas de Ataíde, had the lordship of the honra de Ataíde confirmed by King
Dinis I, in the year 1290. The 1st Count of Atouguia, D. Álvaro Gonçalves de Ataíde, was Gonçalo Viegas' great-great-grandson. ==See also==
