Looking for any relatives of Rene Caisse (1888-1978), the famous advocate for Essiac. She was my great-great aunt. She was 1 of 11 children born to Joseph Louis Caisse Sr (1855-1916) and Friselde Potvin from Lachine, Que (1858-1948) m. 1876 in Petersburg, Waterloo, ON. Joseph had owned a barber shop on Manitoba St in 1912 in Bracebridge. No known parents or siblings exist for Joseph Sr. Friselde's parents were apparently Louis Potvin and Amelia Barrie (Emily Barry). Her known siblings were: Mireza, Joseph Louis, Elzear, Ferdinand, Archibald, and Marie.
