Your father's name is Calhoun so that makes you a little Irish with Scottish Roots. Loch Lomond, Scotland is our homeland, the home of the Colquhouns. My wife's grandparent's name was Williams and they were English so that also puts a little English blood in you. Your mother's maiden name was Riley. That is an Irish name so you have some more Irish blood in you.
You are mainly Scottish with a few English and Irish highlights.
