My english is not very good but I'll try to do my best !
I found a article in the Deziel dit Labreche History about a Charles D. Labreche. I made some research and I found that Charles D. Labreche was not a Deziel dit Lareche but a Dugas dit Labrèche.
Charles D. Labrèche (son of Médard Dugas dit Labrèche and Éléonore Turcotte) born in St-Joseph-de-Maskinongé in 1835. He was a great adventurer in the west USA. He was the first man who made the way of St-Louis, Missouri to Fort Benton on the Haut-Missouri in a little boat.
Charles D. Labrèche married Émélie Hamel the 19 avril 1865 in French Town (Missoula) they have a lot of childrens : Charles R.D., David D., Mary D., Medard D., Lenora D., Emily D., Jessie D. et Théophile.
One of the son of David D. Labreche (born in 1877-1928) married Winnifred Perrine (1/8 blood Piedsnoirs - Piegan Blackfeet) and they have a lot of childrens : Charles, Jessie, Clarence, George, Bernice et Presley-Theophile.
Presley-Theophile married Martha Jo. Barnard in 1944 and they have 3 childrens : James David (Salem, Oregon in 1946), John William (Browning, Montana in 1949) and Laurel-Ellen (Anadarko, Oklahoma).
There is a very interesting things and a new branch of Labrèche (Dugas) in USA. I hope that will help you in your research and tell me if you find more about that ! Good day !
