If I am not mistaken, this is the Old First Ward Cemetery. I don't know much about it, but I don't believe any stones remain there today. I have heard disputed info as to whether the bodies might have been moved. It is a little used park, today. I agree, the OHA would probably be your best bet. Call Tues. - Thurs. 1 p.m. - 3:30 pm, and ask to be put through to the research room.
