Your family connection are very interesting since my great grandfather Moise Tetreault married Adele Authier in St. Hilaire de Rouville 1864. She had a brother Donat who is buried in St. Hilaire. So far I've got 10 children for Adele and some were born in the States. Felix Henri, grandpa, was born in New Bedford, Mass. Moise was a theologian,preacher and professor. he had a lot to do with various parishes in the Easterntownships. Do you have more info on Eugene?
