Episcopal Cemetery

Galveston, Texas
aka Broadway Cemetery
Coordinates: 29.293854, -94.811552
Along south side of Broadway between 43rd and 40th Streets.
It's important to understand that there are seven cemeteries here and the boundaries touch. Collectively, they're usually called Broadway Cemetery. The front cemeteries (along Broadway) are Evergreen, Oleander and Old City with Hebrew, New City, Old Catholic and Episcopal behind. It's easiest to access them from one of the side streets (40th or 43rd) via the alley between them. Episcopal is the southeastern cemetery (nearest 40th Street). The coordinates are for its gate. This cemetery is associated with the Trinity Episcopal Church.
The City of Galveston hosts this aerial view with boundaries marked.

There is a list with about half of the stones photographed at FindaGrave and the Episcopal Cemetery Project has maps and a lot of details but is very slow to load (it's worth the wait). This looks to be an Eagle Scout project - thanks, Eagles!
