My father's full name was Willard Ballentine Reid. That's according to copies of his birth and marriage certificates, and his own CV, written in the mid-sixties when we lived in Winnipeg.
However, his report cards from school have "Ballantyne" as his middle name. I imagine some school administrator spelled my dad's middle name the way the school administrator wanted to, and it never got changed.
All my life I thought he spelled his middle name with a "y", and was blissfully unaware that there might even be the possibility that it was an "e" after the "l"s, and not an "a".
Curious how you can have so much confusion about things like this in a family.
