I'm trying to find my great grandfather,s family.I was told by his daughter that his name was Pierre Ciroi dit Duplessis.Born March 31, 1875 in Canada.He married Delia LeBlanc in 1900 in Massachusetts U.S.A.They had two daughters Pearl Helen DOB: March 31, 1909 and Hazel Ann DOB: July 15, 1912. Pierre's father was Joseph Ciroi dit Duplessis who came from France outside of Paris to Canada and married Elise Aucoin. They had seven children: Mary, Oliver, Damase, Louis, Herman, Lillian, and Pierre.
I was also told that after going to the U.S., Pierre changed his last name from Ciroi dit Duplessis to just Duplessis.However, I have not been able to find him in census records.
If anyone can lead me in the right direction I would appreciate it. Thank you.
