Is the line down the middle?

My brother lives in a rural area a mile or so from my parents on the same state highway. He lives on the east side of the road. They are on the west. The township line runs right on the road–consequently they live in different townships. Is it possible that your “near neighbor” ancestors live in different townships or counties, etc.? That would impact where certain records are kept and stored. Think about where the lines are located and where your family lived.
