In the early 1930s, University of Texas historian Amelia Williams created a definitive list of defenders as part of her doctoral thesis. Her subsequent article, "Critical Study of the Siege of the Alamo and of the Personnel of its Defenders," in the 1933-1934 Southwestern Historical Quarterly, set the standard for identifying Alamo heroes.

Research over the years has added a smattering of Spanish-surnamed defenders, increasing the Daughters of the Republic of Texas list to 189. However, new evidence indicates that much of Amelia William's research was flawed and the number of defenders could actually reach as high as 257.

Most primary links will take you to the New Handbook of Texas Online and to a biography for each defender.  Secondary Links lead to sources within Alamo de Parras.
