My name is Gilles Grondin and I am the president of the "Association des Grondin d'Amérique" (Association of the Grondin in America). We have in our database a Suzette Grondin who may be the person you are looking for.
Unfortunately we have very few information regarding her. Only that she was the daughter of Alonzo, Lorenzo Grondin (1909-1984) and Georgiana Charette (?-?). We know that Alonzo was born in August 8, 1909 in Sainte-Famille-d'Aumond, QC. He married Georgiana on Septembre 16, 1939 in the Notre-Dame-de-Lourdes church, Girardville, QC and died on July 8, 1984 in Timmins, ON. Suzette had one sister (Claudette) and one brother (Roger)
Could you please send me more informations so that we could make sure that she is the correct person.
