I would be interested in knowing more about early house numbering systems I understand that in portions the 1700's and 1800's the houses in a town were numbered in the sequence in which they were constructed. House 41 and house 42 might be in opposite ends of a town. I would like to know when this numbering system began and when it ended. Also, when they went to the numbering system we use now, did they renumber the old houses or were their numbers somehow grandfathered in? Thank you Jim Vleck
