The City may have original field books containing information about the R. O. W. rods. I'd look through those records and any others that may come to your aid. Are there any recorded documents concerning a R. O. W. alteration? So many questions, and the only way to get to the bottom.
Interesting... So, what determines Point-of-beginning? Would the map, that was drawn before the lot was sectioned off, then determine the Point-of-beginning? If so, then the row might vary, changing the actual lot size, more or less on the side of the road, but not on the other 3 sides - they would be determined by the map?
I have been to the county court house, through nearly every minute book in city hall, and contacted the state to see if they had old maps/surveys. Whereas I can show that the city council would be who would determine any change in Row back to the mid-1800's, there was never a vote to change the ROW on this particular street.
