One more thing. The deed for Katherine describes the land as having 10 acres located in the S-1/2 of S-1/2 of NW-1/4 of SE-1/4 of Section 4 Township 29 South Range 36 East. That would mean the property was located directly west of the red-balloon on the Google Map. Walter's land is described as 80 acres located in the S-1/2 of SE-1/4 of the same section which would place it directly south of the balloon. It's possible their house was hidden in the tree canopy. That other building probably belongs to their neighbor's.
Glad I could help out.
