Josephine Vashro (DuCharme) - Who is Josephine's Father?

I have messaged "Martin" the person who entered "Joseph Ducharme" as Josephine's Father. Here is my message to Martin:

Hello Martin, I am your 9th. cousin, James Arthur Vashro Jr. I am currently researching my Great Grandmother (Josephine Ducharme (Vashro - Felix Vashro's wife)) trying to determine who her father is. You have your name on the entry for Joseph Ducharme (Joseph DuCharme) and I am looking for supporting sources of this being Josephine's Father. The latest source that I have come across is Josephine's Death certificate.

I have 3 issues with her death certificate. 1) it lists her DOB as 1861, which conflicts with two census reports, 2) Lists her Father as: "Tuffield" Ducharme (I suggest this could also be "Theophile"), and 3) there is no family member that signed the death certificate - bringing the accuracy of the listed information into question. (as an aside I also a have a membership with Ancestry.com and have a 1855 Marriage document (in French script - which I am not a French speaker!) for Theophile Ducharme and Celina Page (LePage) from Cooperville, New York) Aren't you a LePage?
Sorry for the rambling comments - back to my basic research question: Who is Josephine Ducharme's (Vashro) father?

Thanks for any help you can provide, Jim Vashro
