The BCGS Burial Project has added 142 sites to the searchable map at: https://www.BaltimoreGenealogySociety.org/BCGShome/projects/bcgs-burial-project/.
On the right side of map is a scrolling sidebar. Scroll down to an alphabetical list of the sites. When you find a burial site of interest, you can click on the name and be taken to that spot on the map.
A list of ALL 463 sites (geocoded & non-geocoded) follows the map and is now displayed as a PDF document.
