It is located approximately two miles west of Darien, in the Towns of Darien and Sharon, at 42.5803°N -88.7625°W.[2] [3] [4] It was first named a CDP at the 2020 census, which showed a population of 174.[5]
Philip Allen, a Revolutionary War veteran, and his children: Philip Jr., Harvey, Sidney, Pliny, Asa Keyes, and Persis, came from New York in May 1845, to settle in Allen Grove. Sixty-five Allens traveled by canal boat, steamboat, and overland from Kenosha bringing with them material to build four houses, carpenters to build them, a minister, Bibles, and hymnals. The Allens organized the Congregational church here in 1845. They established a preparatory school for Beloit College in 1856. Philip Junior became the first postmaster in 1846. Philip Allen Sr. is buried in Mt. Philip Cemetery, west of here.[6]
