I am guessing at it here. I believe that his wife was Mary julia Demange. They married Jan 1, 1881, not sure where. His parents would have been Emmanuel Sabourin & Elisabeth Melvina Pare married Apr 16, 1850 in Iberville, Quebec.
Two of his brothers went stateside as Sabraw or Sebra (Napoleon & Louis)
Notes extracted from "Theresa's New England Genealogy" web site:
Emmanuel came to Farnham, Quebec in 1859. He sold his farm in Farnham in
1860 and came to Fisherville, (now Penacook) New Hampshire. He was the
first French family to come to Fisherville. Emmanuel changed his last name to Sebra
when he came to New Hampshire.
