Jordal sons

Here is a photo of Sigri Gunnersdatter and Ole Larson's grandsons.

The photo was probably taken in front of the home of my great grandparents, Ingeborg (Maland) and Omund Jordal and 4 of their sons.    I'm not sure whether it's Olai, Harvey, Martin, Omer, Ernest, Silas, Kinnie or Gordon.
