Death and mariage records of Marie Desdouets in Massachusetts and Maryland

[MartinGoyette23]

Good evening everyone,

Could someone help me find the death record of Marie Joseph Françoise Desdouets (known as Marie Desdouets in the US)? She is the daughter of Louis Joseph Marie Desdouets and Marie Vincente Goaziou and she was born 1894 in St-Pierre-et-Miquelon. She came to the US (Vermont) with her illegitimate child that she had with Joseph Paul Ernest Chesnel. She married Roy Elmer Mitchell in Massachusetts on June 12th, 1920 and she had at least one child with him. I have seen in some family trees on the Internet that some people say she married a John MacDonald and she had at least three children with him (Robert, Glenn and Mary). If the theory that she married John MacDonald is true, I might have found her date of death, but, without the marriage record, it is difficult to prove. Since Roy Elmer Mitchell died in 1979, it means that either the theory of John MacDonald is wrong or that Marie and Roy divorced.

Here is the information I have:
