Hi; In your reaearch of the Beauvais line have you come across Israel Beauvais? He is my maternal grand-father and after 2 years of research all I know is he was born in 1845 and died in 1932 in Ellenburg, NY. He married Delia/Odile Plouffe(dtr of Augustine and Louise Fecteau Plouffe)
Thanks
Ursula
