AUSTIN— Today, Texas Land Commissioner Dawn Buckingham, M.D., is pleased to announce a generous donation of $23,000 from the Texas Society Daughters of the American Revolution (TXDAR) to the General Land Office’s (GLO) Save Texas History Program. This gift will support the conservation of the GLO’s copy of the Adams-Onís Treaty and the translation and transcription of a 1770’s Spanish-era legal dispute document titled “No. 59: Expediente considered at the instance of the resident of the Villa of San Fernando regarding ownership of lands and cattle,” both housed in the GLO’s Spanish Collection.

“It is truly an honor to receive this generous donation from the Texas Society Daughters of the American Revolution (TXDAR),” said Commissioner Buckingham. “Like TXDAR, the GLO’s Save Texas History Program is committed to preserving the story of Texas for future generations, and I thank these incredible women for their support. Through their generosity, these historically significant and irreplaceable documents will be protected, interpreted, and shared for decades to come.”

“The Texas Society DAR is proud to financially support the translation, transcription, conservation, and preservation of these important documents. These projects align perfectly with our mission areas of historic preservation, education, and patriotism,” said Susan Johnston, Texas State Regent, Texas Society Daughters of the American Revolution. “The Adams-Onís Treaty established the United States as a transcontinental power, while the Expediente No. 59 will illuminate the lives of Tejano ranchers and also provide a rich source of genealogical information.”

The Adams–Onís Treaty, a landmark 1819 agreement between the United States and Spain, helped define Texas’s boundaries and shaped the geopolitical landscape of the American Southwest. Under the terms of the treaty, Spain ceded Florida to the United States, while the United States recognized the Sabine River as the eastern boundary of New Spain, thereby relinquishing its claims to Spanish Texas. Unlike most documents in the Spanish Collection, the GLO’s copy of the treaty has never received conservation treatment, contributing to its current deteriorated condition. Conservation of the treaty is therefore essential to ensure its long-term preservation and continued access for researchers and the public.

Additionally, the Spanish Collection document, Expediente No. 59, offers a rare window into the experiences and voices of ordinary Tejano ranchers in 1770s San Antonio. It captures their stories through both collective petitions and individual affidavits addressing community disputes over water access and cattle ranching.
