I have registered with the Lanark County Genealogical Society. I received some information with respect to the Lockhart, Morris and Crampton families.
I have a three page PDF document that I can email to you. It's nicely organized and easy to work with. You may email me at sweetsnsweetie at hotmail dot com
Hopefully, this document will hold some clues and satisfy some of your requirements with respect to information you are seeking.
