Killegrews' Farm in "Shingles for the Lord" (Location)

Res Grier rides his mule to "Killegrews" twice during the story, but the narrative never goes there, and the only real cue to its location we have is that is should take "forty minutes" to ride there, borrow a tool and ride back (17). At this farm live Old Man Killegrew (who is seventy years old), his wife and a cook. Killegrew's age suggests he may no longer be working the farm, and the presence of the cook in this part of the county, where very few of the families have domestic servants, suggests he may be a bit better off than his neighbors.
