Marguerite was born on April 10th, 1882, in the town of Guern, in the department of Morbihan, near Pontivy, in the Brittany region of France to Mathurin Louis (b. September 26, 1855, d. June 12, 1940) and Francoise (nee Allanic, b. April 15, 1882, d. before 1940) Le Dévéhat. She was the third child of eleven known children, five of whom died in infancy, all of those prior to her departure for Canada.

Gaston was born on February 9, 1884, in the town of Chandres, near Chartres, in the Eure and Loire department, in the Centre region of France to Jules Placide (b. September 8. 1850, d. December 12, 1904) and Marie Leontine Josephine (nee Paulmier, b. May 12, 1856, d. Unknown) Rebiffe (or Rebiffé in some records; some descendants, especially in France, have retained the accented "e"). He was the third of seven (known) children, two of whom died in infancy, both before his departure for Canada.

Per a story told to Rick Dondo by Rose (Le Devehat) Kolly in October, 2019...

Gaston fell in love with the family domestic (Marguerite) and wanted to marry her. His father, Jules Placide Rebiffe, disinherited him as a result.

On February 27, 1905, they wed in the town of Sours, near Gaston's home village. Their planned honeymoon was a trip to Canada, arriving in Quebec on April 2, and traveling overland to St-Claude. They were joined by her parents, her sisters Marie-Louise, Mathurine, Marie, and her brother Mathurin. No one else in Gaston's family made the choice of emigrating to Canada.

Interestingly... Marguerite appears as "Margueritte Devehat" on the ship's manifest despite the fact there is a marriage recorded in France prior to their departure. They also (appear to have) married in Manitoba after their arrival, on September 11, 1905. For reasons lost in time, that is the anniversary they celebrated every year thereafter, including, notably, for their 60th which was a grand affair in Winnipeg, reported in the local papers.

Gaston and Marguerite settled on a farm north of Saint-Claude on section #8-7-W1, where they raised a family of nine children. They sold the farm and retired to the town of Saint-Claude. They enjoyed winters with their son Gaston in Maillardville, British Columbia, and always returned to Manitoba for the summer months. In 1951, they decided to sell the house in Saint-Claude and permanently move to Vancouver.

Their favorite pass-time was fishing. While they enjoyed Vancouver, they returned to Manitoba every year to visit family and friends. In 1965, they came to Winnipeg to celebrate their 60th wedding anniversary.

Marguerite passed away on June 2, 1966, in Vancouver. Gaston remained in Vancouver and passed away on May 19, 1975.

Both their remains were brought back to Manitoba and laid to rest in the Saint Claude cemetery.

Further:

As noted above, she was mentioned on the manifest of the SS Vancouver, as arriving on April 2, 1905, in Halifax, NS, from Liverpool, England among 63 members of the following families, nearly all from Guern or nearby villages, all destined for Red Deer in what was to become Alberta, but a missionary aboard convinced them all to head for St-Claude, instead:
