In another record, there is a description that indicates the character 善 in his name 金忠善 (Kim Chung-seon) may have also been in his Japanese name, and a person with a name 鈴木善之 (Yoshiyuki SUZUKI) in the Saika group was confirmed in Japanese records.
また、別の記録から金忠善という名前のうち善の字については以前から名乗っていた可能性を示唆する記述があり、日本側の記録でも雑賀衆に鈴木善之という名前の人物が確認できる。
