You did not give me must to work with.But this is what I was able to find.Please check the names as they might not be the same family you are researching.In my research, there was a Rene and Louis who were brothers at one point living in Montreal and yes Louis around 1962 was living in or around Hull, Ontario.This is the family which I have researched.
I.-Francois-Xavier Forest married Hilda (Exilda) Archambault on April 19, 1869 L'Epiphanie, PQ. This couple has at least three children (1) Joseph the father of a Rene and Louis, (2) Ozina, and (3) Valmore.
II.-Joseph Forest (son of F-X and Hilda Archambault) married to Olivine Lebrun (daughter of Michel and Algae Blais) on September 14, 1897 Montreal, PQ. This couple had at least six children (1) Rene who died at the age of 56 but I was not able to find his birth date who married Isabelle Ouelette on June 28, 1926 Frenchville or Fort Kent, Maine.There were no children listed for this couple but Celina Levesque was noted as Rene's mother. Could this be the aunt which you mentioned? (2) Gerard born September 15, 1899-died September 15, 1972 Montreal who married Eva Duval. This couple had the following children Bernadette, Guy, Louis, Michel, Rosaire, and Gisele.(3) Bernadette born August 8, 1902 St-Pie, Bagot, PQ-died July 14, 1943 Montreal and married to Edgar Genest. (4) Marie-Jeanne born November 12, 1903 St-Pie, Bagot, PQ. (5) Louis-(Joseph) born March 14, 1905 St-Pie, Bagot, PQ and married to Marie-Ange Leonard on January 2, 1930 Notre-Dame, Montreal.This couple moved to the Hull area and had the following children Edgar, Micheline born June 6, 1931 Montreal was married to Jean-Raymond St-Cyr on February 25, 1952 in Hull, Mireille born August 28, 1934 who married to Jerome Cyr on October 11, 1958 at Notre-Dame de Grace, Hull, and Pierre.
