Sorry! Was away and failed to return to this thread.
I went over to the Recorder of Deeds Offfice to look at the history of ownership of the Mason property and cemetary where Charles Taze Russell was buried (pyramid). I have the old deeds showing the transfers.
The Watchtower TO THIS DAY controls a small plot of land in the NORTHEAST section of the Mason property. The pyramid and grave of Russell? Yeah... they're located SOUTHWEST of the buildng.
Of even more interest, there is a plot of land on the Recorder's map that is marked "unassessed property" that appears to fit the dimensions described in the Deed. I'm told that unassessed could mean a burial site. If I had read the deed before I left the office I would have seen the connection and would have gotten a copy of the property picture.
I now know how to post pictures so I'll scan both deeds this evening for everyone's review. The only thing left to retrieve is the picture.
