While "data doctoring" I came across this problem -- Ormstown apparently disappeared from 1964 to 1982.
On the "drop down" list of choices it appears as Ormstown, Quebec, Canada East, and Lower Canada all to 1964. (We know that both Canada East and Lower Canada ended long before 1964.) Then, starting in 1982 it is Ormstown, Le Haut-Saint-Laurent, Quebec, Canada.
Just sharing this with a smile. No reply needed.
