The Washington (Missouri) Historical Society lists the Richard Farrar family cemetery in Boone Township, Franklin County, Missouri:

http://washmohistorical.org/cemetery.htm

Census records and published biographies indicate that it was not far from the Jesse Farrar family cemetery which was located on Farrar Road, 41N 3W Sec 3.

The Richard Farrar cemetery was the family cemetery of probably both Richard Farrar and his wife Lydia Harrison and their son Richard Jr. and his wife Nancy Jane Thurmond. It was on the old homestead of Richard and Lydia which continued to be farmed by Richard Jr. and Nancy. Neither couple are buried there, but graves would include the two of Richard Jr. and Nancy's children who didn't survive to adulthood as well as that of their daughter Lillian who died age four in 1891.

Richard's brother Jesse P. and his wife Mary L. Bullock established their home and cemetery on an adjoining piece of land which they had also acquired from Jesse and Richard's parents.

Richard Fenton Farrar, Jr. family history:

The son of Richard Farrar and his wife Lydia Harrison.

He married 7 Mar 1860 to Nancy Jane Thurmond, daughter of Bennett Thurmond and Pharlina Calviard.

From "History of Franklin, Jefferson, Washington, Crawford and Gasconade Counties", Goodspeed Publishing Co.; pub'd 1888.
"Richard Farrar is a native of Franklin County, Mo., and was born December 8, 1832; he is the seventh of the eight children of Richard, Sr., and Lydia (Harrison) Farrar. His educational advantages were those of the common schools, and his life was spent on the farm with his parents until their deaths, the father dying in 1879 and the mother in 1873. March 7, 1860, he was united in marriage with Nancy J., daughter of Bennett Thurmond. They are the parents of eight children, of whom six are living, viz.: Thomas J., Emma (now the wife of J. W. Calvird), Richard B., Charles E., Arthur F. and Lillian.
Mr. Farrar still owns the old homestead of his father, consisting of 574 acres, to which he has made an addition, and which is well stocked with cattle, sheep, horses and hogs. He is also a member of the firm of R. Farrar & Son, of Champion City. A stanch Republican, he has never aspired to public office, having preferred the life of a quiet citizen, respected by all. He is one of the leading and substantial farmers of the county."
