Your are right Henri was born 1814 according to his tombstone. The only child I know of for sure is Josephine Parent. B-Sept 19, 1859 in Canada d-april 20, 1902 in Occum, Ct. per death certificate, Marrie
Napoline Desmarais, when & wher I do not know perhaps in Woonsockett, RI Working on it. Had Omer, Phillip, Charles and Zenobie Desmarais. Napoline died. Josephine married Adelard Anthony Gadue. Again where or when I am not sure. Probably second marriage around 1894 as first child Hilda was born Sept 1895 Adelard & Josephine had Hilda, Irene and a baby that died in childbirth which is also when Josephine died.
