Denver genealogist, Henrietta Elizabeth Bromwell collected and indexed the names of gold miners seeking their fortunes who arrived here in 1858 and 1859. These miners were called the '59ers. She published this collection in 1926 as the Fifty-Niner's Directory, Colorado Argonauts, Pikes Peak Region.
A complete listing of the index is available online through the Denver Public Library, Western History Collection.
While she does not list C. W. Arbuthnot, she does have his company and two of of the four sons that came with Carson. I've also included some others who were at the 1860's miner's meeting when C. W. was voted in as Constable.
While Ms. Bromwell has done an excellent job of acquiring this information, some of it, I have found, is not accurate. Evidence will show that William Arbuthnot returned to the Boulder area before 1864. We don't know how many trips back and forth the Arbuthnots made to Iowa, but we do know there were several trips made between the two areas.
Here are a few of the men from the Fifty-Niner's Directory, Colorado Argonauts.
ARBUTHNOT & COMPANY, mentioned in papers of 1859 as mining in placers of Pleasant Valley, and working two men.

Clerk also of School Board. He married Mar 29, 1870, Miss Mary R., daughter of J. P. Johnson of Left Hand.

BLORE, William R., arrived Auraria Nov 2, 1858. Was one of the discoverers of the famous Horsfal Lode, in Gold Hill, which gave $10,000 in two seasons, with sluices. This was in Jun 1859. He was born Otsego County, New York 1833, of German descent. Resided as a child Erie County, Pennsylvania. In 1856, Nebraska (Sarpy County). After coming to Auraria he was one of the stockholders, assisting in laying out town, helping to build its first log houses. He mined and prospected in several places, but preferred Boulder County. Was President of the Gold Hill Mining Company, and several others. In three years the Horsfal Lode made $300,000. He had a ranche, which he sold and later was in the War, at the Battle of Sand Creek. He returned “to the States” and later, after returning, bought large ranche.
