In May, 1922 three local African-American men were lynched in Kirvin by being mutilated and then burned alive for the alleged murder of a 17-year-old white girl, Eula Ausley. Some 500 local whites, including the girl's grandfather, took part in the killings. Evidence now points to the innocence of at least two of the three victims. This notoriously gruesome piece of vigilantism was followed during the next month by several more instances of lynching by hanging of other black men in the area.  
A Book by Monte Akers titled Flames After Midnight: Murder, Vengeance, and the Desolation of a Texas Community was written about the infamous incident. 
The Town of Kirvin is served by the Wortham Independent School District.
