Served in the Revolutionary War. Capt. Ream’s Co, 3rd Battalion, Lancaster County, Pennsylvania, Active Militia. Active in the Pennsylvania Militia until 1795.

Moved to Augusta County, Virginia around 1800. He died while visiting his son Jacob’s wife.

Weyers Cave, “discovered” and named by Bernard Weyer in 1804, was on the property he purchased from Henry Bingham in 1819. Peyton’s History of Augusta County, Virginia (1882) describes the network of caves as vast and sublime, even “exquisite.” The discovery brought tourists, and Mohler home, at first a simple cabin, became a fashionable country inn. The 21-room brick home was supported in no small part by the work of the family’s slaves.

Also known as the Grottoes of the Shenandoah, the caves were renamed Grand Caverns in 1926, declared a National Natural Landmark in 1973, and gifted to the Upper Valley Regional Park Authority the following year. By then named Grand Caverns Regional Park, it became the property of the city of Grottoes in 2009.

By 1889, the cave was owned bythe Grottoes Land Company.
