It has been passed down that Sorin, who had succeeded as a merchant (financial business) through the connection, assisted Chikurin-in, the legal wife of Nobushige (Okane's mother and a daughter or adopted daughter of Yoshitsugu OTANI), throughout her life after Nobushige died in the Siege of Ozaka.
その縁で商人（金融業）として成功した宗林は、大阪の役で戦死した信繁の正妻（おかねの実母で、大谷吉継の娘あるいは養女）竹林院を生涯に渡って援助したと伝えられる。
