Daigo Tadataru (醍醐忠善)
Tadataru DAIGO (1819 - 1820) was a retainer of the Imperial Court during the latter half of Edo period. His father was the minister of the center Teruhiro DAIGO. His mother was the daughter of Yoshihisa HACHISUKA of the Tokushima domain. His foster father was Tadayoshi ICHIJOU.

Right after he was born, he was adopted by his head family, the Ichijo family. Although he was one of the family heads of the Court noble Daigo family, who had the house status of the Seiga family, he died early at the age of two. His final official court rank was Jugoinoge (Junior Fifth Rank, Lower Grade) which was given when he was conferred a peerage.
