I have an 1881 census record for my Ontario ancestors which lists as its census place Olden, Addington, Ontario. But it sure looks to me like Olden Twp is in Frontenac county. Was there an Olden village, perhaps? Were lines redrawn sometime after 1881? Any help you can give me in this matter will be appreciated (PS It also says Distrcit 118, Sub-district 1, Page # 18...if that helps any.)

In the 1871, 1881, and 1891 census Addington was an enumeration district. It has no bearing on geographic county locations. Olden Township is geographically within Frontenac County.
