Version 7.1 of the list (pdf) has only a few new buildings, by far the most interesting of which is one that Hugh Lamb advertised on the back of the 1877 Newark city directory:
Martin’s Villa (Fairmount?), Chatham, N.J.
This might be the grand mansion built on Long Hill (Fairmount Avenue) by William A. Martin of New York, a wholesale liquor dealer (or tea importer?). It does not look like Fairview House, the long-time hotel apparently established by a William Martin.
Incidentally, Lamb first appears — as an architect — in Newark in a directory published in 1868. He seems to have been a draftsman, but the directories do not indicate which firm he was with. He would have been only 19 or 20.
