The community now known as Ulmer goes back for many years. The surrounding lands belonged to only two persons - Ephriam Ulmer and John Williams. There are authentic records dating back to the 1700s. The ancestral home of the John Williams family still stands. It was lived in until sometime in the 1950s. The first building was erected on the banks of the Salkehatchie River. The site was near a settlement know as Buford's Bridge - which was there prior to the Revolutionary War.
