The Search for Frederick Douglass’s Birthplace
Markers in the Landcape
Frederick Douglass told a Baltimore audience in 1877:
Satellite imagery and 1875 map of Caroline County, Md., were used to locate the site of an African-American church near an upper crossing of the Choptank River.
I recently digitized a paper copy of the map of Caroline County, Maryland, which was drawn by John B. Isler in 1875. While geo-rectifying sections of the map (stretching and warping the images to match the “ground truth”), I noticed a building marked “Col Ch” on the road east from Goldsboro, at the crossing of a branch of the upper Choptank River.
