Cordelia had the following siblings:
Regina (Marie-Anne), Edmond, Joseph-Ulric, Pierre-Victor, Alphonse and two half siblings Majorie and Philippe.
If you wish to know more goggle to "The Ricard of North America" and follow the path from Jean, Charles-Simon, Michel2, Francois5, Andre, Ulderic, Elzear, and Cordelia.
Cordelia had the following children: Bernadette, Irene, Diana, Roger, Antoinette, Therese, Yvette, Alice and Albert.
I hope that this helps.
