This collection consists chiefly of correspondence regarding the Runge family of Galveston, Tex. and Menard, Tex., including Henry Runge, his sons Henry J. Runge and Louis Hermann Runge, their cousin Julius F. Runge, as well as family members in Hannover, Germany, including heirs Hans Eyl and his wife Meta Eyl; German immigrant and Texas businessman Walter Tips (1841-1911) who, after the death of Henry Runge, had formed the Las Moras Ranch Company (December 21, 1879) with his wife's aunt Julia Runge, wife of Henry Runge, and Runge's sons Henry J. Runge, and Louis H. Runge; German Emigration Company lands, lawyers and law firms in Austin, Tex. and San Antonio, Tex., including C. A.

Also present are: legal documents, including deeds, wills, powers of attorney, some ranch operations records, including ranch inventories, accounting ledgers, and handwritten notes. These papers record the operations and transfers of ownership of over 130,000 acres of property, principally in the Texas counties of Comal, San Saba, Tom Green, Concho, and Menard, collectively known as the Las Moras Ranch.

Beyond the acquisition, operation, and ultimate liquidation of this ranch property, however, an interesting part of Texas history, that of the Adelsverien or German Emigration Company, and early German immigrant settlement are illuminated through the documents in the collection.

The collection series reflect the history of the ranch from its foundation until its sale in 1913.

• Series 1 begins with an 1867 legal document showing a transfer of ownership of many thousands of acres of land from Hermann Arnold Henry (Heinrich) Runge (1821-1861) of Funchal, Madiera, Portugal to his brother and business partner, Henry Runge (1816-1873). Henry Runge paid for the land in American Gold. Other documents in the papers include a very large judgment against the Adelsverien or German Emigration Company, a copy of the lengthy handwritten "Last Will of Henry Runge," probated April 2, 1873, and that of his wife, Julia, dated March 23, 1896.
• Subsequent documents in Series 2-Series 4 of the papers highlight the operation and eventual liquidation in 1913 of the Las Moras Ranch, including transcontinental communications between Germany and Texas among heirs to the Runge fortune. Several of these family letters scattered through the papers may be particularly difficult to translate since they are written in Kurrentschrift, a Gothic handwriting style.
• Playing important roles in the later transactions concerning the ranch properties were the sons of Henry Runge (1816-1873): Henry J. Runge (1859-1922), Louis Hermann Runge (1861-1936), and his nephew Julius F. Runge (1851-1906). Henry J. Runge and Julius F. Runge were financial advisors, while Louis Runge served as the ranch manager and lived on the Las Moras Ranch property. Walter E. Tips (1841-1911), another German immigrant, Texas Senator, and successful hardware merchandiser, who married into the Runge family, along with C. A. Goeth (b. 1869), a San Antonio attorney, were involved in the ranch operations and legal issues concerning the eventual dispersal of Las Moras Ranch property.

This collection consists mainly of correspondence, legal documents, a corporate minute book, and handwritten notes recording the litigation connected with ownership of a large tract of land (89,000 acres) in Hidalgo country known as the "Big Santa Rosa Pasture". Actual litigation took place from 1903-1910.

Individuals involved in the case were: Dillard Rucker Fant and his wife, Lucy Fant; Daniel J. Sullivan; J. C. Sullivan; James V. Upson; Wiliam R. Elliott; Conrad A. Goeth; James Webb; J. M. Chittim; Archie Parr; Kate V. Elliott; G. G. Clifford; A. E. Chavez; J. A. Galligher; W. M. Sanford; Fred Kelly; F. A. McGown; F. W. Church; H. R. Wood; F. Groos and his wife, Hulda Groos. Legal counsel involved in the proceedings were: James E. Webb and Conrad A. Goeth of Webb and Goeth, F. A. McGown of Denman, Franklin & McGown, and R. L. Ball, all based in San Antonio, Texas.

At the onset of the difficulties, D. R. Fant had leased the Big Santa Rosa Pasture to the cattle-raising partnership of Chittim and Parr. J. M. Chittim was a large rancher in South Texas and Archie Parr, was a State Senator popularly known as the Duke of Duval. Based on the large annual rent monies Fant had expected to collect from Chittim and Parr, he then also borrowed money from D. Sullivan of D. Sullivan and Company Bankers (founders and owners of the large South Texas Mariposa Ranch) and, using the same collateral, borrowed more money from the competing F. Groos and Company Bankers (later a founder of Wells Fargo Bank).

When it appears, that Chittim and Parr defaulted on their rent payment for the Big Santa Rosa Pasture to Fant, Fant was then forced to default on his own payments to both banking organizations from whom he had borrowed funds. The bankers, in return, sued and foreclosed on the Big Santa Rosa Pasture.

Through the Santa Rosa Ranch Papers extensive set of legal documents, attorneys' memoranda, telegrams, letters, and financial disclosures, the most absorbing story of Texas land politics unfolds.

Notable among the papers is the Santa Rosa Ranch Minute Book, a ledger volume with handwritten entries detailing the Articles of Incorporation, By-laws and minutes of the first stockholders' meeting of the Santa Rosa Ranch Company. Also present is a manuscript plat map in black and red ink on light blue linen, of the 1905 Maria Rodriguez survey, which has been encapsulated and is housed separately in a Map Case Drawer.
