Wikipedia doesn’t have a history of Kemps Mill yet. The photos, dates and memories neighbors add here are how it gets written.
Kemps Mill is an unincorporated community and census-designated place in Washington County, Maryland, United States. Its population was 126 as of the 2010 census. It is named after a 1739 built mill structure which still stands in 2020 and has operated under a variety of names through almost three centuries. The mill dam creates a slackwater which is popular for fishing and other recreational water activities. The mill is several miles above the mouth of the Conococheague Creek which flows to the Potomac River at a location where Native American trading posts existed for many centuries prior to European settlement in the area.
Between the 2010 and 2020 censuses its population fell from 126 to 117 (-7%).
