I'm looking for info. on my gr-uncle Trefflé Gastonguay or Castonguay, married to Marie Boisvert on Jan 12, 1858 in Baie du Febvre, Qc., and remarried later to an unknown person. I have a picture of him made by a professional photographer: A. Benoit, Main Street, Danielsonville,Ct. and it is said he died in the u.s. I thank in advance anyone with info on this person or his descendants, and if desired, will share a couple of photographs I have of him.
