This list (except for the rightmost column) is compiled and transcribed from a summary of the (original) Heyrick (1694) document, which is stored in the archives of the British Library and confirmed against the updated Heyrick (1695) list. The 1695 document is part of the collection of the Institute and Faculty of Actuaries (which is also the cover image of the book). The number of years lived, in which (only) a lower bound is provided is based on the King (1730) surviving nominee list and the Anonymous (1749) surviving nominee list, which are both available in the British Library. The nominees listed with an exact number of years lived is based on (i.) the assumption that their deaths were recorded in chronological order in the final page of the King (1730) list, and (ii.) the number of nominees who died in every year is based on the JHC (1803) document.

Presumably, Finlaison (1829) himself had access to the exact death dates of all the nominees on this list, since he compiled one of the earliest English mortality (and life expectancy) tables based on this tontine. Alas, I haven't been able to locate the Finlaison “list,” but I would love to get my hands on it.
