Dalley * , Nielson B.

Nielson was born Feb. 22, 1861 in Summit, Iron county, Utah. (He is usually referred to as Nels.) At the age of 18 he was called to accompany the group selected to explore the San Juan County with the idea of settling this section of the state. Being a good rider and very handy with cattle, he was assigned to help with the livestock that accompanied the explorers. (Kumen notes in his journal that Nielson Dalley was from Cedar City.)
He accompanied James B. Decker, Kumen Jones, Parley Butt, and Hamilton Wallace back to Moencopy for the Davis family, who had remained there because of the ill health of Mrs Davis. They also brought the cattle and some horses on to Fort Montezuma. (His journal of southern exploring party of 1879, included in Hole in the Rock by Miller pp 148-154)
He returned later to his home in Summit and later married Mary C. Jones, Feb. 21, 1883. They were the parents of nine children. Mr. Dalley was a farmer and sheepman all his life. He died Aug. 30, 1947 (Saga of San Juan 307)
