I was born in Ottawa and my Janveau family has lived there since my great grandfather. My father came from a family of 7, I have 7 cousins from that family and they also have children. My family was originally immigrated to Montreal then to Upper Canada. I do know there are a lot of Janveaus in the Montreal area. We are all related one way or another. The family's name was Viau in France. Some of the family changed there name to Jeanveaux, Jeanveau, Janveau.
If you would like to contact me I could give you what I have.
