According to the 1930 census, there was a Lorenzo E Fecteau, age 36, and his wife Victoria, age 35, living in Methuen, Essex county, Massachusetts. (He was in Lawrence, Massachusetts in the 1900 and 1920 census records).They had two children listed: Cecille M, age 8, and Paul E. age 7.
From what you give in your posting, I believe these are the people you are looking for.I have their ancestry back to the 1600's.
Please get in touch with me so that we can exchange information.
I also had (but not connected to the above)a Lucien N Galarneau of Hyattsville, MD (but formerly of Lawrence, Mass) with two children: a daughter who married Paul Facteau and a son Claude Gerard who married Barbara Wheeler of Washington, DC.
So this may also be the people you name in your posting.I would like to confirm this.Thanks.
