Captain Heinrich Joseph Richarz established this cemetery in 1905. A native of Prussia, he and his family arrived in Texas in 1850. After a brief stay in Bexar County, the family moved to Fort Lincoln, residing for a time in quarters once occupied by future Civil War General James Longstreet. Richarz soon bought nearby land, moved his family there, and raised cattle and Merino sheep, which he is credited with introducing to this part of the country. Frequent Indian raids led to the organization of the Medina Mounted Home Guards, and Richarz, with his military background, became its major. In 1870, he was captain of Company E, Frontier Forces, based at Fort Inge near Uvalde. His son Walter, a private in this company, was killed by Indians. At D'Hanis, Richarz established the first post office west of Castroville and served as its postmaster. He also served as chief justice, or county judge, of Medina County, as a cattle and hide inspector, Fourth District school director, and as a representative to the Seventeenth State Legislature. After years of public service, he retired to his farm and died on May 21, 1910. He and other members of his family are interred here.
