Looking for Selene Joseph formerly of Demtoco

I am a Guyanese living in the US for 35 years now and am trying to locate Selene Joseph, formerly of Demerara Tobacco Co. She resided in Toronto, Canada 1974-1977, where she gave birth to a son Laurence, before returning to Guyana. She attended the Seventh-day Adventist Church on Church St. Her parents lived on the East Coast. Anyone with information can contact me at LLFarnell@gmail.com orLfarnell@signatureny.com; Any information would be greatly appreciated.
