His mother was Kyoun-in (Onabe no kata [Lady Onabe]), and Nobutaka ODA was his older brother by the same mother (although in reality, he was born in 1576 and was younger, but according to the order of precedence within the Oda family, Nobutaka was situated higher and therefore he was treated as his older brother for convenience sake).
母は興雲院（お鍋の方）、織田信高は同母兄（ただし生年は1576年で、実際には信高の方が弟であるが、織田家中の席次は信高が上位であるため便宜上、兄とされている）という説が一般的であるが、当時の一次史料からは確認できず、異説もある。
