This series consists of materials assembled and used for background research about the Sangre de Cristo Land Grant, its history, ownership, and original settlers and descendants. Most of the folders contain photocopies and/or typescripts of original documents from books, archival repositories, or courthouse files. Materials include court decisions, court transcripts, deeds, directories, letters, surveys, and more. Original documents found here include court case documents, including some from cases pre-dating Rael v. Taylor, as well as some correspondence. Files are arranged following the index at the start of the series, which is roughly alphabetical, along with additional folders found interfiled but not listed. Two files are restricted to Council board members and attorneys.
