The story so far

from Wikipedia & the U.S. Census

Allen Township is one of thirty-seven townships in LaSalle County, Illinois, USA. As of the 2020 census, its population was 531 and it contained 245 housing units. Allen Township was formed from Bruce Township on an unknown date. The township bears the name of Allen Stevens, a pioneer settler.

Between the 2010 and 2020 censuses its population fell from 584 to 531 (-9%). Half of its homes were built before 1942.

Wikipedia doesn’t have a history of Allen yet — the old photos, dates and memories neighbors add here are how it gets written.

Nothing in Allen is on the National Register yet

That’s true of most small towns. It doesn’t mean Allen has no history, only that no one has written up a nomination. The closest listed place is Ransom Water Tower in Ransom, 0.4 miles away.

How a place gets listed

1Talk to the stateEvery nomination goes through the State Historic Preservation Office. Owners, towns and historical societies can start one.
2Try a local or state list firstMany states keep their own register with a shorter form, a common first step for old barns, halls and schoolhouses.
3Write it upA nomination covers the history, photos and a map. Ransom Water Tower’s page links to a real one.
