I would not have any possibility to know any of the persons on the Photo since I am a dane living in Denmark.
But the brother of my granpa lived in the area in that period. He was called Lars Ledet and had first a farm near Lorenzo, then he lived a few years in Rigby and then for a long period he had a farm near Ririe. He told in letters home, that he - a bachelor - visited very often in weekends other Danish people in the area. And vice versa.
That is why i now ask you, if you ever have heard of a Lars Ledet, visiting the Andersen Family or could have an idea if there could be a source to find out about him and his doing there.
