Happy Saint Patrick's Day! Yes, I am Irish. The photo is of The O'Brien Tartan Plaid. Isn't it beautiful? The O'Briens on my family tree goes back to 1135, but there are many other names listed as well, such as O'Connor, Kennedy, O'Kelly, MacWilliam, MacNamara, and on and on. Although all of these people are on my family tree, my Irish percentage is small, but I still claim it proudly. How Irish are you?
