Poolesville, Maryland used to have the legal name of "The Commissioners of Poolesville".
South Orange, NJ at one time had the official legal name of "the Township of the Borough of South Orange Village" (including three of the four legal municipality types in New Jersey in its name). This was caused by switching from the Village to the Borough form of government as most municipalities in NJ did in the early 20th century, then later switching to the Township form of government because the federal government was really bad at understanding what NJ meant by "Township" and at one time offered subsidies to such places as if they were rural and unincorporated, even if they were not. Even today, it's still the Township of South Orange Village.
I see this was covered (in less detail) above.
