This being a 'late' map the house areas are not well defined but the Green #20 area, lot? 22 is the Governor/General E.A. Perry's home, now the Scottish Rite building. Just below that in the pink area # 118 and 116 are about where the Mallory and Chase homes stood. This map list courthouse and that's where the old Federal court was until they disgraced us and tore down the San Carlos Hotel to build another Fed Court that couldn't open when it was s'posed to cause it had mold and some 'unexplained' problems. Anyhow. I had forgotten the Sanborn maps. Thanks for slapping my memory.
Going to check the Fl Archives site. They have a bunch of photo's on line and hope the ones I'm talking about are some of them.
