Sylvanite ?
Formula: (Au,Ag)2Te4
Description: "supposedly occurs"
Reference: Januzzi (1976) Mineral Localities of Connecticut & Southeastern New York State
Tellurium
Formula: Te
Description: A careful reading of Silliman (1819a, 1819b, 1819c) indicates the tellurium was not native but chemically extracted from ferberite, which was also not from Monroe, but from the unique ferberite after scheelite deposit in Trumbull also worked by Ephraim Lane. Their origin was cleared up by Hitchcock and Silliman (1826). Januzzi misreads Silliman and mentions "tellurides" in his publications. Because the ferberite crystals from Lane's Mine of Trumbull have the shape of scheelite crystals (they are pseudomorphs with which he had no experience and was quite perplexed by) he thought he had a new mineral with tellurium in it. Silliman never mentions tellurides and his extraction of tellurium from ferberite has never been replicated.
Reference: Silliman (1819a, 1819b, 1819c); Hitchcock and Silliman (1826); Januzzi (1976); Samuel Robinson (1825) A Catalogue of American Minerals, with their localities. Boston
Topaz
Formula: Al2(SiO4)(F,OH)2
Description: Probably from topaz-quartz-muscovite-fluorite veins that occur within and around Old Mine park in northern Trumbull and extend into adjacent Monroe.
Reference: Januzzi, 1976. Mineral Localities of CT and Southeastern NY State
Tungstite
Formula: WO3 · H2O
Description: Original descriptions by Silliman (1822) and Bowen (1822) indicate the type material was found intimately associated with both unaltered scheelite and pseudomorphs of ferberite after scheelite unique to Lane's Mine of Trumbull, also worked at the time by Ephraim Lane. Samples were sold and shipped to Silliman, he did not collect them. Origin of the ferberite and scheelite was eventually cleared up by Hitchcock and Silliman (1826).

Uranophane
Formula: Ca(UO2)2(SiO3OH)2 · 5H2O
Description: Reference provides no details, but its occurrence is very plausible.
Reference: Ryerson, Kathleen. (1976) Rock Hound's Guide to Connecticut.
'Wolframite'
Formula: (Fe2+)WO4 to (Mn2+)WO4
Description: Original descriptions by Silliman (1819a, 1819b, 1819c) match the pseudomorphs of ferberite after scheelite unique to Lane's Mine of Trumbull (not Monroe), both places worked at the time by Ephraim Lane. Samples were sold and shipped to Silliman, he did not collect them. Origin was eventually cleared up by Hitchcock and Silliman (1826).
Reference: Silliman (1819a, 1819b, 1819c); Hitchcock and Silliman (1826)
