About comment by Douglas Delack ...
The article says that he arrived in Ogdensburg nearly 50 years ago (1820-1830). He and wife Margaret/Marguerite show up as Dulac in 1860 US Census, but I haven't been able to find them in the US before that. I do have strong evidence of them for the 1825 and 1851(2) Canada Census.
