1796年、署名者の一人であるトマス・マッキーンは、宣言の署名日が7月4日であるということに対し異議を唱え、署名者の中にはその日以降に会議に選出された者を含め、その日には出席していない者もいることを指摘した[3]。マッキーンは、「その日も、その後何日も、誰も署名しなかった」と書いている[4]。1821年に出版された『会議の秘密日誌』(Secret Journals of Congress)により、マッキーンの主張が支持されるようになった[5]。『秘密日誌』には、宣言に関するそれまで未発表だった2つの記述があった。
4日に可決された宣言は、"The unanimous declaration of the thirteen united states of America"(アメリカ13州の全会一致の宣言)というタイトルとスタイルで羊皮紙に公正に刻まれ、その後に会議の全メンバーによって署名されることが決議された[7]。
^Friedenwald (Interpretation and Analysis, p. 143) says that 45 delegates can be confirmed as present on July 4, and that another four might have been.
^Friedenwald (Interpretation, p. 149) gives the number of non-signers as seven, not counting Dickinson, who absented himself for the final votes.
^Friedenwald (Interpretation, p. 149) lists seven men; he does not include Charles Carroll of Carrollton, who had been working as an emissary for Congress. He did not become an official member of the Maryland delegation until July 4, and did not take his seat as a delegate until July 18. (Hazelton, Declaration History, pp. 529, 587)
