From FindaGrave:
The children of Colonel Dresbach were moved to this cemetery from the family plot in 1960 due to the expansion of Interstate 90. The oldest dated tombstone is for Jessie Dickson who died September 1, 1871 at the age of one year. There are 330+ marked graves. This is still an active cemetery.
