[1] Nathanial and Hannah Armstrong, formerly residents of Virginia, arrived in southwestern Ohio in 1800; they soon built a log cabin and gristmill on their land and began farming.

[3] Nathanial Armstrong provided that the church be made available for the use of whichever denomination had the greatest number of members in the vicinity.

Although the foundation was built of fieldstones and held together by soil rather than mortar, it has moved only slightly; a restoration performed in the 1970s demonstrated that the building had settled just 2 inches (51 mm) in 140 years.

[6] In late 1975, Armstrong Chapel was listed on the National Register of Historic Places by the name of "United Methodist Church."

As the congregation grew in the early twenty-first century, a new building was deemed necessary; a groundbreaking ceremony was held at the end of August 2009, and the new structure was substantially completed in October of the following year.
