My great-great grandfather, Lucien Edward Turcotte, was born in Quebec (probably Saint Henri, Chambly, Quebec) to Augustine/August Turcotte.Augustine married twice: first to Euphersene Bejan and second to Christine (last name unknown).Christine was a widow and living with Lucien Turcotte according to the 1900 ND Census.
Lucien married Marilda Fortier and had 15 children. They arrived in the U.S. before 1878 and applied for land in Spink Co., S.D. in 1889.They moved in 1893 to Cando, N.D. and Rolla in 1896.
Second hand family information says Lucien was one of several children.The only other confirmed sibling is Joseph Adelard Turcotte, b. 1852/3 in Quebec.He died 1934 in Towner County, near Rolla, ND.He was unmarried.
Names of possible siblings are:Anaisse Turcotte Chabot/Cabot; John Turcotte; and another Joseph Turcotte.
I have come across the name Louis Turcotte several times during my searches of the N.D. sites.The name Josephine is used frequently throughout my Turcotte line, too.
I don't know if any of this info assists you but it would be lovely to find a link between the two families.
