I have Exire (AKA Elzier, Exiri and Elyse) Fontaine death in Ste-Cecile-de-Milton, Shelton, QC from "Deces de Ste-Cecile-de-Milton, Shefford, Quebec" at 79 years. How do you have her connected to Connecticut?
I have her birth 29/30-Apr/May-1859 in (Ste-Cecile de) Milton, Shefford, QC (with questionable 1901 census source and baptism). Baptised 30-Apr-1859 in Ste-Cecile de Milton, Shefford, QC (without source).
I have her parents as Edouard Fontaine dit Bienvenu and Mathilda Elizabeth Dextra dit Lavigne. Connection probably made from the birth/baptism, but I don't have the source recorded to prove this. A good place to check is the original Drouin records on Ancestry.ca. Unfortunately I don't have access to these records at this time.
I don't have the details on her first marriage to Alfred Part (Partie?).
