Here is something from 1980..60% of Lewiston had French as primary language then..I had no idea...

And it appears there are two strains of Franco-Americans in Maine..the Acadians and the immigrants from Quebec and probably New Brunswick. I have no idea at all if there was direct immigration from France. I think there are therefore two language strains. The Lewiston area would probably have been people, often single women, coming to work in the textile mills. They said often three generations of one family stood at one loom over the years..wouldn't that be a great song?

Also, I imagine a very few French-sounding names could have come from Ireland..I have a French-named ancestry and my niece married an Irishman also with French history. Wonder where all those Fitzgeralds and Fitzmaurice etc. came from?   mg
