Sylvio Chouinard B1890- 1900?

My grandfather was Sylvio Chouinard.He was married to Jenny St. Hilaire.I do not know sylvio's parents name, but I know that he had brothers whom he lost touch with after WW1.I believe they settled somewhere in the United States.Sylvio had one son (George Joseph Emile) and three sisters (Blanche, Gabriele, & Eva).
Any info on this family would be greatly appreciated.
Thanks
