this is the information I have, although I am not sure it ties in with your branch.I don't see an "Ida" anywhere.
My father, Lloyd Rivers (formerly Noah Rivers...he changed his name at an early age)had 9 siblings.They are: Gertrude, Ellen, John, Mildred, Joseph, Rafael (died in infancy), Clarence, Marie and Ruth.
The parents of this group were Helen Marcoux and George Rivers (LaRiviere).Helen Marcoux, my grandmother, sometimes referred to herself as Ellen Marcoe, Ellen Marceau.Her parents were Jean (John)Marie Marcoux (your grandfather?) and Ellen Snow.Jean Marie Marcoux's parents were Jean Marie Marcoux Sr., and Mathilde Angelique Tremblay.Ellen Snow's parents were Isadore Snow and Sophie Cyr.
Gertrude, incidentally, was the eldest of my aunts, so she must have been born in the 1880's.
