Thayer's Notes:

a His historical interests extended to the writing of at least three works, none of which reached a wide audience, however: a Prize Essay On The Relations Of The Different Professions And Vocations To Longevity (Francis Hart & Co., New York, 1873); Henry Sater, 1690‑1754. Sater genealogy with addenda and index (privately printed, New York, 1897); and his most ambitious, The Life of Rev. Archibald Maclay, D.D. (Polydore Barnes Co. Press, New York, 1902: an edition limited to 500 copies), the subject of which was his grandfather, a prominent Baptist minister in New York.

b Isaac Maclay was present at Ford's Theater when President Lincoln was shot, and helped transport the President to the room in which he died. Some of the details are given in the linked obituary.
