I found Dennis' family on the 1851 Canada East Census with six children listed as Flansburg. I was told he had 10 children but can't find them listed anywhere. The 1851 census lists six children and their ages: Ellen (Hélène born about 1837), Emile (female, born 1839), Stephen (born about 1841), Jane (born about 1844), Denison (Dennis, born about 1846), and Margaret (born about 1849), and my grandfather Henri or Honoré (born 1859). Then, they disappear. Where did the family go? I have yet to find information on Emile, Jane, Eleonora and Julie, if they were his children?
He married Julia Ann Levan (sourced). Did he remarry a Marie Josephte Lavergne? Haven't confirmed Lavergne yet or was that a misspelling of Levan? And can't find Levan's death record, or Dennis' marriage to Marie Josephte Lavergne, if that's his second wife.
I need your help! I've looked everywhere. If anyone has any leads or sources that's even better, please let me know. Anything is appreciated!
