The London Enemies List seems to have been a list of 59 men who were considered to be a danger to the crown. I found a couple of sources that suggest the list was drawn up by London Tories, but these both use David Fischers "Paul Revere's Ride" as their source.
The table in the question is reproduced in full in this paper. The footnotes to the table state that the original document containing the "London Enemies List" is held in the collection of the Massachusetts Historical Society.
A transcript of the document has been published (although this lists 63 names, rather than the 59 quoted in the paper referenced above). The document is dated 18th April 1775.
The online transcription notes that the original document was gifted to the Massachusetts Historical Society by the Hon. C. F. Adams in 1869.
The list is also one of several datasets that were used to demonstrate how metadata could be used to analyse social networks. The others are political organisations and clubs in the Boston area of which Paul Revere was a member. Most of these datasets seem to also be headings on the table you referenced.
Rather than using current data about living people, the authors decided to use lists of groups from the Revolutionary War to illustrate how effective this metadata could be in analysing social networks, and identifying potential "terrorists in the American colonies". With tongue firmly in cheek, the author observes:
Rest assured that we only collected metadata on these people, and no
actual conversations were recorded or meetings transcribed. All I know
is whether someone was a member of an organization [sic] or not.
Surely this is but a small encroachment on the freedom of the Crown’s
subjects. I have been asked, on the basis of this poor information, to
present some names for our field agents in the Colonies to work with.
It seems an unlikely task.
The reason I mention this is that the article includes links to the datasets used (i.e. the lists of names of people in those groups) on GitHub, which might be of use to you in your research.
