An Albert Supernault died at the age of 100 in Ellenburg Center (Clinton County) during late 1920's, probably in 1927, although I am not absolutely sure. He was born on August 14, (1827??), in St. Edward, Canada, and came to Ellenburg as a young child with his parents. He is buried in St. Edmund's Cemetery in Ellenburg Depot.
Suprenault is not one of my family lines, so I don't know anything else about Albert. If your Isaac lived in Clinton County, maybe a check of St. Edward, Canada will turn up something.
