The Texas Department of State Health Services has downloadable files of marriage license application and divorce indexes, organized by year. These are records that are available through other sources, usually for a fee, but if you want to work directly with the data yourself, this is the source. The marriage index covers 1966 through 2005; divorces include records filed from 1968 through 2005 . The marriage files have 140,000 to 166,000 records; each divorce file has between 50,000 to 87,000 records. The files are compressed and require a zip extractor but can also be purchased on CD, which may be a better option if you don’t want to store them on your hard drive.
