Shigemasa OTA was one of her elder brothers, who is included in the Toyama clan's family trees (refer to the Musashi-Toyama clan in "Record of Family Trees") and may have been raised on the mother side of his family (the Toyama clan) with Eishoin after his father's death like as if the both had been a brother and sister.
兄として太田重正があげられるが、重正は遠山氏の系図に含まれており（武家家伝の武蔵遠山氏参照）、父の死後その母方（遠山氏）で英勝院と兄妹のようにして育てられた可能性が考えられる。
