Fecteau origine
I do not thing that your ancester has falled from sky or came from France.
She was rather coming from the area of Beauce Québec. Probably around 1870 1880. A firt wave of emmigration occured from Beauce in this time.
If I was you I woudl begin in Ste-Marie (Beauce) and after St-Elzéar.
There was also Some Fecteau in the area of Thetford-Mines Québec not far from Beauce.
The first mine of asbestos in Thetford was on the land of a Fecteau.
I have on my lineage a Virginie Roseberry who maried a Louis Fecrteau at Brougnton alway in Beauce.
Does that help you a litle
Clément Roseberry
