I had previously thought that Foucault and Noyan were 'replacement' names for Christies and Caldwells Manor that came into use as the 'Manors" ceased to be used; and that these were later changed into names like Clarenceville and Henryville with some corresponding boundary adjustments. I am presently checking some marriage records for marriages in the early 1830s and find these names are being used at the same time implying they were distinct places. Viz. in 1834, 1835 and 1836 I find references to each of Noyan, Caldwells Manor, Clarenceville and Henryville. Does anyone KNOW (i.e. have a reliable reference source) that explains when these various names ceased being used or came into use? I already have Matilda Day's work and some old maps but neither seem to answer this confusion. Possibly what I am seeing is no more than sloppy book keeping in the records.
