Do you happen to have a copy of the 1861 census for Camden East Twp. Lennox and Addington County. It appears that Joshua Long and Elizabeth Brown are living with a Clement family. I wanted to see what the relationships were to the family. I have found the marriage of Charlotte Long and Ira Davy which lists John Long and Ann Clement as Charlotte's parents. I have also found the marriage registry of Henry Long and Mary Nelson, again listing John Long and Ann Clement as Henry's parents. The census may be the record that links Charlotte, Henry and Joshua being brothers and sister, as well as the link to the Clement family.
