The individuals hat you write about are actually Louis Vitalis Lefebvre (LaFave) and his wife Delima Sequin. They would be the parents of Alexina Lafave Houle. Alexina LaFave Houle was born in Ste. Justine, Quebec Canada on December 25, 1881 she was one of 10 children born to this couple. Mrs. Houle has a grand-daughter a Mrs. Clark that lives here in Tupper Lake, NY now.
My father Daniel Lefebvre, this is the correct French Canadian spelling, was a nephew to Louis Vitalis Lefebvre. My grandfather Napoleon Lefebvre was a brother to Louis Vitalis. There are still a number of relatives in Tupper Lake who are nephews, nieces etc. to Mrs. Alexina LaFave Houle.
Delima Sequin was born I believe in Ste. Justine, Quebec herself the daughter of Antoine Sequin and Emelie Chantelois. Louis Vitalis was born in Ste. Marthe, Vaudreuil County Quebec on June 26, 1854 the son of Louis Lefebvre and Celanie Roussin. He was the eldest of 13 children.
I hope that I have been of help to you, please let me know. I do have some additional information.
