A specimen of "a very heavy black stone" was sent by John Winthrop, grandson of Governor Winthrop to Sir Hans Sloane of the Royal Society. It was described as the first columbite crystal by Hatchett in 1802, over 50 years after John Winthrop died. A "barely legible" label may have said something like "Nautneauge" but there is no such known place. Trumbull believed it was found near Winthrop's mill, a short distance above the head of the Mystic. (Dana's 6th ed). Mitchell reported the location as a spring at New London, but probably refers to either Middletown or Haddam. However, Dana (1875) says that "No locality has since been detected at that place." That it came from anywhere in New London county is speculation and columbite bearing pegmatites are not known from the area.

New London is underlain by Late Proterozoic rocks of the Avalonian micro-continental terrane, mostly grey gneisses, primarily the New London, Potter Hill, and Rope Ferry plus the Hope Valley Alaskite gneiss. Small stocks of the Narragansett Pier Granite intrude the area, but it is not an area known for pegmatites.

| ⓘ 'Mica Group' ? Description: As the mica was coating the columbite, and its origin in New London is very doubtful, this mineral is also suspect, at least in this case. Reference: Mease, James (1807). A Geological Account of the United States (Philadelphia: Birch & Small), pp. 421-423. |
