What drives Twin Lakes’ History grade
On its age, its old homes and the National Register, Twin Lakes is more historic than 33% of U.S. towns, #278 of 362 in Wisconsin. Its share of homes from before 1940 holds the grade up; its National Register listings pull it down.

HistoryA character grade: shown, never part of Twin Lakes’ overall grade.
Wisconsin towns list more on the Register than most of the country (a typical Wisconsin town has 3.0 per 10,000 residents, the U.S. 2.4), so Twin Lakes’ 0.0 sits below most of its state (28% of Wisconsin towns have fewer) while its 0 listings outnumber those of 23% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from C− to C+. The pre-1940 share is a Census survey estimate (±4.8 points). The founding year is the first post office, not a stated founding date.

What stands out about Twin Lakes’ past
Read from the archive, the National Register and the record. The page puts what stands out first.
Mary Rae, a native of England was born June 15, 1816. She came to America in 1833 and resided in what was to become known as “English Prairie”. In 1837 she was married to Jonathan Imeson, also an early settler on the prairie. Their son Robert was the first born son of European descent in the county. There were eight children in all, including the first set of twins born on the prairie. The girls were baptized Mary and Elizabeth. Both lakes were named after these girls, Lake Mary & Lake Elizabeth, which extended into Illinois, and almost to the English Prairie.
A post office called Twin Lakes has been in operation since 1891.

The Twin Lakes post office opened in 1891, the earliest record of the town by name (U.S. post office records).
