The historical marker at the site reads:
Zion Cemetary, comprising 15 acres, was established in 1876 by the United Sons of Zion Association, a group of former slaves who responded to the need for a respectable burial site for African Americans. It is the final resting place for many outstanding citizens. Including Georgia Patton Washington (1864-1900), who was one of the first female African American physicians, and Thomas F. Cassels (1850-1903), who was Assistant Attorney General of Shelby County and a member of the Tennessee General Assembly.
You’re probably wondering, “Why Memphis and why this cemetary?” Well, one of the couples in our group, Gene and Jill, are good friends with a couple of people who started/planted/founded/whatever you want to call it, Fellowship Bible Church of Memphis. Fellowship, along with other civic groups in Memphis, has been actively involved in recruiting volunteers and groups to help clean up the cemetary. They pitched the idea to Gene, Gene pitched the idea to us and we were in. You should check out the church’s web site. They’ve got a cool vision: racial reconciliation in a city that desperately needs it.
Here is a Google Earth satellite image of Zion Cemetary. That big cluster of trees in the middle of the picture is what remains to be cleared. The baseball field to the left gives you an idea of the scale of the project.
