Bad example.
For starters, the name alone should be a clue - Sweeney being Irish. She also has Scottish, German, English, French Canadian, and as the shape of her eyes and cheeks obviously indicate, Native American. Oh, and in one account she has a whopping 3/16 Norwegian in her! Bingo! You hit the jackpot on that one.
Hate to say this, but that 3/16 definitely does not account for that curvature. Got to travel a wee bit more south for that.
