Scaramouche on Family Tree Circles

I am looking for my ancestors and would like to find out>
1: What happened to my grand parents:Cleophas Cote who died between 1909 and 1915 and Marie Riendeau who died between 1910 and 1915 in Montreal Quebec, Canada.
Do I have some relatives still in Montreal? I would love to meet them.

2:My father Arthur Cote was born early 1910 and placed in an orphanage ie. St-Cun?gonde,Montreal( but not for adoption)in 1915.He studied and lived with the nuns until 1923. Then the grey nuns placed him with a farmer in St-Valentin Quebec Canada. The name of the farmer was Mr.Gaudreau. My father had a sister named Yvonne Cote and a half brother named Armand Dubois, son of Marie Riendeau's first marriage w/..Dubois.DO YOU KNOW ANYTHING REGARDIND ARMAND DUBOIS AND HIS FAMILY?

3:I Have cousins in USA probably in the NY State. I would love also to know them.My father's sister Yvonne Cote Left Quebec and went to USA were she died. She was married and I beleive she had 2 sons. Her husband was very sick in 1958 when I visited him in the hospital. I cannot remember his family name consequently I cannot find my cousins without finding someone who knew Yvonne Cote and her family or knows her sons and family. Any help would be appreciated.
