I don't know if this helps you out or not, but I am involved with Brian Plante. His father is Larry (Laurier) Plante. I do know a Rosemary Cote. She is Larry's aunt and Brian's great aunt. Let me know if this helps. I know that several Plante family members were born in Maine and many of them went to Pennsylvania. A lot of them, I am guessing are still in Canada. Let me know if this helps. There may be no connection at first, but eventually, there will be. Thank you.
