East side of Auburn-Folsom r. on Tanglewood Way., Loomis, Placer County, California. This cemetery is located on private property.

Also I found this decription:

On an oak-covered knoll a short distance from the Auburn-Folsom Road near Horseshoe Bar Road is the Prosser Family Cemetery, and it remains as a memorial to the hardships and grief endured by settlers in Placer County. There is no superlative wording on the two remaining grave markers, but what is there tells the story of a large family which suffered illness and death as its members struggled to survive in the 19th century.

It is not known when the Prossers settled in Placer County, but Barbara Van Riper of Ophir, a distant relative who has researched the history of the Prosser family, said William J. Prosser purchased 240 acres of what was known as the Mason Ranch to raise cattle. The area was known then as the Franklin District. "There were 10 people buried in the cemetery," she said. What is known from the engraved names on the granite stones is that William J. Prosser and his wife, Nancy Jane Prosser, lost three children before they reached the age of four months. Prosser died in 1894 at the age of 78. His wife was 48 when she died in 1876. Two daughters they wanted to name Nancy after their mother died in 1861 and 1868. One was eight days old and the other three months and eight days. The aged, spire-shaped marker also had the simple engraving "Infant Son" on one side. Beneath it was the religious offering of "Suffer little children to come unto Me for theirs is the Kingdom of Heaven." There also are the names of Minnie M. Prosser, who was less than one year old when she died in 1866, and C. J. Prosser, who succumbed in 1871 at the age of six months. The names were on a stone along with the other infants, but there were no inscribings indicating they were the children of William and Nancy Prosser. Another large grave marker, one that had been broken and repaired, marks the site where 23-year-old John G. Prosser is buried. He died May 28, 1871. There also is interred Kate H. Threlkel, daughter of the Prossers, who was married to G. L. Threlkel. She was the grandmother of Burton Threlkel, who lives in Cool. Kate H. Threlkel, who was the mother of two children, reportedly died during childbirth November 17, 1876, at the age of 23. The Prosser Family Cemetery, one of a number of family cemeteries in the county, has been uncared for in recent years. A house was built in the area, according to Burton Threlkel. He said some years past the grave of his grandmother was violated and her remains removed. The Prossers and Threlkels, an early-day family that joined Brigham Young and his party on a pilgrimage west, left their mark in making the county what it is. They endured difficulties, pain, and heartbreak during the days of limited material wealth and convenience. The Threlkel and Van Riper family cemetery is located off Rattlesnake Road. It too is a symbol of the men and women who, as pioneers, came, survived, and died in their chosen new home, becoming part of the heritage of Placer County.
