The 2015 summer Dallas Genealogy Society Summer Symposium: Researching in Texas was held August 7-8, including an after-hours session at the library until 10:00 on Friday night. The speakers covered a lot of Texas history, and the types of documents that are available in different archives for each period. Of special interest was the discussion on the archives at the Texas General Land Office.
Although many records are available online at the GLO website through the Land Grant Search, the Surname Index shows some of the documents that are not available online; for these we will have to make a trip to the GLO. We both have enough for a couple of days of research; there is a trip to Austin in our near future.
The presentations on the special collections at the University of Texas at Arlington was partcularly helpful in figuring out what questions to ask and what to expect when trying to find a home for collections.
