My cousin Ruth is unable to reply to your query so she asked me to. Neither I nor another Latimer researcher Ruth and I know have your people in our databases, but I see Richard & Harriet (or Harriett) in Lehigh Cemetery acc to "Some Kitley Cemeteries" (Pub#80-2, April 1980, L&G Branch Ontario Genealogical Society). Entry#115 - "Richard C. Latimer 1866-1948/ his wife Harriett A. Mott 1866-1925 / Cecil E. 1889-1890/ Richard H. 1901-1902." Also, #116-"Richard Roy son of Roy & Hazel Coon d. May 4 1920 age 1 days" Hope this helps!
