^Jacob was always written with a 'c' in the records of Walldorf's Reformed Church, but Walldorf's Rev. Georg Speyer spelled the name with a 'k' in his laudatio for Astor's 50th death-ceremony and from then on the name remained that way in Astor's hometown. (see Herbert C. Ebeling. Johann Jakob Astor zum 150. Todestag, 1998, p. 2).
