The story

How Ash Grove Township came to be

From Wikipedia’s history of Ash Grove Township.

Read it all →

Ash Grove was initially settled by Euro-Americans by 1830. It was an early location of Mormon missionary activity in Illinois, with Mormons residing there by 1832. In late 1836 a mob attacked a Mormon missionary preaching at Ash Grove. Younger Green got an affidavit for the arrest of the mob, but the militia refused to cooperate in arresting the accused mobbers.
