My brother-in-law had an aunt that married Thomas Henry Tyo of Calgary, AB. He was born in Glengarry County, ON. The Tyo name was originally spelled Taillon, but later changed to the phonetic spelling. Thomas' grandson, Mike, can be emailed at:
myto@tyobio.com I've no idea if this is the same family, but the Tyo name has been researched by others.
