I am trying to find a date of death for Marie-Louise (Girard) Ducharme. She was the wife of Flavien Ducharme. She is alive in Woonsocketm RI in the 1910 census and Flavien is a widower in Fall River by 1920. He is listed in the Woonsocket Directory up until 1916, vanishes until 1920 in Fall River. Any ideas as to where I should look next? ?
