Aloha Chris, BONAMI dit LESPERANCE is not my line but I know a little about Raymond. He was a soldier with Montcalm's Army in the War of Seven Years (Guerre de sept ans). He undoubedtly came to Canada in the late 1750's. He originally came from the Parish of Talense, Diocese of Carpenteras in the County of Avignon, France. His parents, who apparently did not come to Canada, were Jean BONAMI & Gabrielle MIAULET. On 16 APR 1762 at Chambly, Quebec he married Marie-Madeleine THIBODEAU (of Acadian ancestry). M-Madeleine was the widow of Jean-Baptiste ST. PIERRE. Present at the wedding was 7-month-old Raymond BONAMI who as best as I can figure was an illegitimate son of M-Madeleine and was adopted by Raymond. This info comes from PRDH and a series of articles on "Les soldats de la guerre de sept ans" appearing in "Memoires" the journal of the most prestigious French-Canadian socoiety in the world, La Societe Genealogique of Montreal. The info on the origins of Raymond and the marriage from the two sources is amazingly similar, so you can probably cast most of the above in concrete.
For info French soldiers of that era were required to take a second name when they enlisted. So if you were to trace back to France you'd probably find that Raymond's father was Jean BONAMI (without the LESPERANCE). My ancestor Jean LANDIE dit LESPERANCE fought in the same war. I found his enlistment in the French Army archives. I returned last week from 5 weeks in France which included hosting at breakfast 15 LANDIEs from the region where the Jean the soldier originated.I was honored with a meeting with the mator of the twon where my soldier was born.
