I am looking for my half-sister, and any other siblings I don't know about that my mother might have had after my sister.
My birth mother's name on her birth certificate was: Celina Lionel Thivierge, but she went by Leona Thivierge. Her DOB was 5/11/16. Her parents were Adelard and Exilda Thivierge and they were born in Canada, but Leona was born in Amesbury, MA. Leona had a least two sisters, Yvonne and Rita Thivierge.
Leona married my birth father, Leopold Dube, on 6/15/35 in Amesbury, MA and they lived in Amesbury for a couple of years, and then she moved to Newburyport, MA. I was given up for adoption and then my birth mother had my sister on 10/12/40.
My sister's name is Joan, but I don't know if that is her legal name or a nickname, like Leona's name is a nickname. I know my birth father is not Joan's father, so I don't know what Joan's last name was. My birth mother eventually remarried and I believe she was living in NY in mid-late 1940s. I don't know what her married name was.
Can anyone help me with this?
Thanks
