Rose-Anna Charron-Ducharme (AKA Osanna) was indeed born March 19, 1859, in St-Félix-de-Valois, QC. Her father was Ephrem Charron-Ducharme (your birth and death dates for him are OK), and her mother was Henriette Desrosiers-Lafrenière. Ephrem and Henriette were married July 6, 1858, in Ste-Elisabeth, QC. Rose-Anna was their oldest child, and 13 more followed from 1859 to 1884.
Now, according to my files, Rose-Anna married a man named Joseph Nault (Joseph + Angèle Desrosiers-Lafrenière) around 1875, in Lowell MA. Hence, she was 16 when she got married.
I have no information about her being married to Louis Girardin of having a son with the name Salomon.
Rose-Anna died on Dec. 03, 1935, in St-Félix. Joseph Nault died 26 days later, on Dec 29. At her burial, she is said to be the wife of Joseph Nault. Her brother Ephrem was there, as well as Noé Longpré, her brother-in-law, and William Malo and Alfred Joly, her sons-in-law.
There is certainly a mystery here. The only thing I can see to match your data with mine is that Rose-Anna may have married first Louis Girardin, that may have died early. Where did you gor the info about a marriage between Rose-Anna and Louis Girardin?
