ジョン・ジェイコブ・アスター
Even though some sources refer to Jakey as John Jacob V, John Jacob Astor, 1st Baron Astor of Hever (1886–1971) was born first and therefore is actually John Jacob Astor V. Sir Jakie Astor (1918–2000), youngest brother of David Astor, was John Jacob Astor VII; the 3rd Baron Astor of Hever is John Jacob Astor VIII. Jakey is sometimes (incorrectly) referred to as John Jacob III.
