In Manor, Texas, there is a street named John Nagle St. It is close to the old Southern Pacific Railroad. My great grandfather was John Nagle (from Austin) and his son, my grandfather was named Caldwell, also a street in Manor, not far from John Nagle St. This seems to be more than coincidence. Does anyone have any idea of how I can pursue the namesakes of these streets to see if they are named for my family members? Any help would be most appreciated.
