The Mailloux Family Tree

I am researching the Mailloux family. Joseph Eli Mailloux was born October 19, 1907, in Montreal,Canada, the son of Lucien Mailloux and a step mother named Aurore Poulin. He moved from Canada to the United States as a young adult, served in the U.S. military, and was married here. He died June 08, 1968, in Rochester, New Hampshire.

I am looking for information on how he first came to the United States,who moved here with him and any available information on these people and their relationship to him, the name of his natural mother, and any information on his natural relatives. Rumor has it that he was adopted.

Any information would be appreciated. I am also willing to share the information that I have.
