Robert Millot was the son of Jean Millot and Adélaid Robert who were married in the same church on September 25. 1830. Jean was a "cordonnier" - a shoemaker. Jean Millot was the son of Joseph Marie Millot and Catherine Wilcott. The story of Robert Mylott's grandparents is here.
Jean Millot and Adelaid Robert did not emigrate to Whitehall with their son - at least not permanently, but they did leave Vercheres. Their death records can be found in the church records of St Jacques le Mineur, south of Montreal and a few miles north of the US - Canadian border in the high Richelieu River Valley in.
