The town in Quebec where Pepere Gagnon was born is called L'Islet-sur-Mer, a tourist village according to a website entitled quebecvacances. They also decribe the village as having its "lands caressed by the tides". This map provided by Google shows its proximity to northern Maine. Shown to the right is an image of the Notre-Dame-de-Bonsecours Church in the town as it looks today. Pepere Gagnon may well have attended this church as a child.
The article goes on to say that Mr. Gagnon worked on the railroad for nearly fifty years. In a taped recording from 1990, his daughter, Bernadette, recalled that he was gone so often that he was like a guest in the house. She remembered as a child that he would bring gifts home such as tubs of butter or bars of maple syrup. In the 1926 Westbrook City Directory (pg. 127), he was listed as a foreman for the Portland Terminal Company. On Wikipedia, the Portland Terminal Company is listed as a terminal railroad and was known for its control of switching activity for the Maine Central Railroad. PTM's activities were vital to Portland's role as a winter seaport receiving Canadian products for shipments to Europe.
In doing my research for this article, I found a really cool 1930 map (above) showing all the railroad lines in New England. Mr. Gagnon worked on the Rochester, NH to Portland segment for five years according to the Westbrook American article. In a recent conversation with his grandson, Roland Albert said that he held a pretty important well-paying position for someone without an education.
Other guests who attended Mr. Gagnon's 90th birthday party included four daughters and two sons: Mrs. Ovide Harvey, Mrs. Albert, Mrs. Rocheleau, Armand Gagnon all from Westbrook, Mrs. Leon Casey from Philadelphia, and Edward Gagnon from Lewiston. Also in attendence: 35 grandchildren and 29 great grandchildren!
